New Symptoms Following Rituximab Treatment in MS Patient
A 16-year-old female was diagnosed with multiple sclerosis (MS) around two months prior, with optic neuritis being her sole symptom. She received her initial infusion of rituximab two months ago, but has recently experienced unusual symptoms that began about a week ago. Initially, she noticed a buzzing sensation on the right side of her head, accompanied by a feeling of pull in her eye. As the week progressed, the buzzing sensation intensified, and she started to experience brief episodes of numbness that affected her left arm, hand, and leg, lasting only a few seconds. Last night, she observed an odd feeling in her hand, but initially dismissed it as a figment of her imagination. However, upon waking this morning, she realized that the peculiar sensation was indeed real. She does not experience any weakness or significant numbness, but during finger tapping exercises, her left hand feels somewhat less connected. She describes this sensation as subtle, rather than overtly pronounced. Somewhat concerning to her is the fact that she had a recent lesion on the right side of her brain when she received her infusion. This raises the question of why these symptoms have emerged at this point in her treatment.

It's understandable to be concerned when new symptoms arise following a treatment like rituximab, especially in a young patient with multiple sclerosis (MS). The symptoms described, such as buzzing sensations and brief numbness, could be related to various factors, including the natural course of MS, effects of the medication, or possible new lesions.
Explanation
New neurological symptoms after starting treatment could be influenced by several things:
- MS Symptom Fluctuation: MS can cause symptoms to vary widely, and new sensations can sometimes emerge as the disease progresses.
- Rituximab Effects: While rituximab is used to manage MS by targeting specific immune cells, some patients may experience short-term neurological changes as their body adapts or reacts.
- Lesion Activity: The previously noted lesion on the right side of the brain may still be affecting her neurological function, particularly in terms of sensory perceptions and motor control.
Next Steps
Here’s how to approach these new symptoms thoughtfully:
-
Symptom Monitoring: Encourage her to keep track of the frequency, duration, and nature of the buzzing sensations and numbness. This can provide valuable information about whether these symptoms are trends or isolated incidents.
-
Assess Activities: Identify any potential triggers or activities that might exacerbate her symptoms (e.g., stress, fatigue) and consider pacing activities accordingly to avoid worsening sensations.
-
Mindfulness and Relaxation Techniques: These practices can help manage anxiety about symptoms and may provide relief from sensations. Simple breathing exercises can be beneficial.
-
Engage With Support Networks: Encourage her to discuss these experiences with others who understand MS, including peer support groups, which can provide reassurance and coping strategies.
-
Routine Communication: Maintain clear communication with her healthcare providers regarding the new symptoms. It might be helpful to prepare a concise summarization of the symptoms to share during future appointments.
If the symptoms worsen, or if she experiences new severe symptoms (like persistent weakness, vision changes, or loss of coordination), it would be important to seek further medical advice sooner. Reassure her that MS symptoms can be variable, and it's important to focus on her overall well-being as she navigates through her treatment.

Persistent Toenail Problems Not Linked to Fungi
At 33 years old and diagnosed with Ehlers-Danlos syndrome through genetic testing, I’ve been experiencing troubling symptoms with my toenails for approximately three years. Specifically, the inner areas of my big toenails have begun to show signs of damage and have become detached at the same location on both nails simultaneously. Despite undergoing antifungal treatments, there has been no improvement whatsoever. The affected regions fluctuate in size as my nails grow, yet they remain persistent. My Ehlers-Danlos syndrome also contributes to flat feet, a condition I've learned may correlate with my toenail issues. Recently, I consulted with a podiatrist who seemed perplexed by my situation. He expressed skepticism about the possibility of these conditions persisting for years without any growth or rejuvenation in my nails. After examining the situation, he confirmed that there was no fungal infection present. An X-ray revealed that the arch support in my right foot is considerably diminished, which aligns with the greater damage seen in the toenail of that foot. He recommended that I use insoles, take meloxicam for discomfort, and schedule a follow-up in six months. I’m reaching out to see if anyone has insights into the potential causes of my symptoms. I suspect that my toenail problems may stem from the way my feet align within my shoes. I’ve also experienced toenail loss; they become discolored and eventually detach after spending prolonged periods on my feet in supposedly comfortable footwear. Additionally, when my toenails grow excessively long, they encroach upon adjacent toes and lead to bleeding. Could this misalignment be a contributing factor? What remedies might help? I’ve experimented with various shoe styles, and while I notice slight improvements in winter when wearing boots, the issue persists. Unfortunately, I can't provide a visual reference as the platform doesn’t allow image uploads. I appreciate any suggestions or insights!
Worsening Concussion Symptoms and Anomalous Scan Findings
Patient Information: - Age: 23 - Gender: Male - Height: 5 feet 9 inches - Weight: 215 pounds - Current Medications: Cymbalta and an assortment of vitamins and supplements. Greetings. For several years, I have endured debilitating symptoms. However, since last October, my condition has escalated to the point where I am confined to bed. I’m dealing with persistent and severe symptoms that are reminiscent of a concussion. Experts suggest that my case aligns with a chronic illness known as MECFS, for which I meet the diagnostic criteria. Yet, my recent scans yielded unusual results that raise concerns: - "There is a tortuous pattern observed in the bilateral distal cervical internal carotid arteries." - "Slight hyperplasia has been noted in the right cervical artery." I am genuinely worried that my health is deteriorating, and I fear the possibility of a stroke. Nevertheless, every emergency room physician and neurologist I have consulted seems unfazed by my symptoms and the scan outcomes. What are your thoughts on this situation?
Concerning Skin Changes on My Abdomen
I am a 22-year-old male, standing at 5'8" and weighing 160 pounds. I am Caucasian and currently taking Duloxetine. Recently, I've observed the development of dark, uneven patches moving up the right side of my abdomen. These areas are firm to the touch and are devoid of hair growth. The texture is smooth, but they alter the appearance of my skin. Over the course of the last year, these patches have progressively worsened. In addition, I have been experiencing ongoing abdominal discomfort. It’s worth noting that these skin changes first emerged while I was on Duloxetine. Should I consider scheduling a doctor’s appointment soon?
Struggling with Unexplained Symptoms for Four Months: Could it be Long Covid?
I am a 31-year-old guy standing 6'02" and weighing 200 pounds. I contracted COVID-19 in mid-2022, which severely affected me for a fortnight. I was bedridden, experiencing intense discomfort, fever, and a persistent cough, needing ample rest to recuperate. After those two weeks, I returned to my usual state of health and vitality. Throughout my life, I've maintained an active lifestyle, engaging in weight training and cardiovascular workouts almost daily for the past 15 years, with a resting heart rate typically hovering in the 40s or 50s depending on my cardio routine. Fast forward to December 2024, I fell ill with a significant flu for about a week. Although I felt unwell, I managed to continue working as a police officer and only took a single day off due to my symptoms. I opted not to undergo testing for COVID-19, as this flu felt typical for me, unlike my previous experience with the virus. Following this bout of illness, I returned to my regular activities—gym workouts, work, and socializing—without any issues. In February 2025, while doing home renovations and preparing to lay new floors, I worked with a self-leveling compound. The following day, I spent several hours using an angle grinder to address uneven surfaces in an enclosed area. I utilized a vacuum attachment for dust control and wore a flimsy KN95 mask; however, I ultimately removed it midway through, resulting in significant exposure to dust. Even though I was surrounded by dust, I didn’t experience any immediate coughing or irritation, so I dismissed it, but in retrospect, that seems like a poor decision. The next day, I felt well enough to go to the gym, but after just one set of bench presses, I noticed an alarming shortness of breath. It felt as if my lungs were constricted and unable to expand fully, almost as though I’d been knocked the wind out of me. This sensation has persisted ever since. Concerned, I sought emergency medical attention the following day, as my breathing difficulties did not ease. I also experienced severe sleep disturbances that night, waking up every couple of hours and struggling to fall back asleep. This insomnia has continued unabated. Since that fateful day, I’ve experienced numerous other symptoms, including: - Shortness of breath - Ongoing insomnia - Hair thinning - Persistent tinnitus in both ears - Occasional tunnel vision - Numbness and tingling in my limbs - Rapid onset of numbness when lying on hands and feet - Longer-lasting skin imprints from pressure - Increased sweating - Intermittent night sweats - Bloating after meals - Overall fatigue (which has seen some recent improvement) - Hand tremors that worsen after exertion - Internal tremors during adrenaline spikes - Elevated resting heart rate (now between 60s and 70s, compared to my usual 40s to 50s) - Increased blood pressure - Variable oxygen saturation levels, predominantly between 95-100% but with occasional drops into the low 90s without intensifying other symptoms - Some exercise intolerance. Over the past four months, I have sought medical care repeatedly, undergoing several diagnostic tests, including four X-rays (one each month), a CT scan, a PET scan, and various blood tests—all of which returned normal results. There are no indicators of inflammation, damage, or any abnormalities. I have consulted several general practitioners, a couple of pulmonologists, and two therapists who considered anxiety as a possible contributing factor, as suggested by my primary care doctor. When I informed one of the pulmonologists about my potential silica dust exposure, he assessed that silicosis from a single event was unlikely, given my symptom presentation differed from typical cases he had encountered. I expressed my concerns regarding irreversible damage, but both pulmonologists reassured me that silicosis would not develop swiftly and would show signs in tests. Sadly, my medical team seems puzzled by my symptom cluster, having exhausted various treatments with no success, including Prednisone, multiple inhalers, benzodiazepines, hydroxyzine, trazodone, Zoloft, and Lexapro. None of these medications have alleviated my primary concerns: the shortness of breath and sleeplessness. I suspected sleep apnea but noted that my oxygen levels remain stable during sleep (measured by a smartwatch), and I do not wake gasping for air. Nonetheless, I have scheduled a sleep study for further evaluation. I also explored numerous supplements to address potential GERD or vitamin deficiencies, but none have yielded positive results. Repeatedly, at least three of my doctors have mentioned that my symptoms mirror those seen in patients with long COVID. I did experience fatigue during a specific period where I could barely get out of bed, but that has improved significantly, allowing me to resume some semblance of my previous activity levels. I’ve taken up cardiovascular and strength training again and was pleasantly surprised to find that around 70% of my strength remains intact. However, my endurance has drastically diminished; I could previously run 3-5 miles at a 6:30 minute pace, whereas I now struggle to cover 2 miles at a 7:30 minute pace. After these sessions, I am drenched in sweat and observe that my heart rate stays elevated in the 90s to 100s for a couple of hours, compared to the 50s it used to return to within an hour. When I raised this with my pulmonologist, he seemed at a loss, as his typical patients are often suffering from severe COPD and are not presenting with the specific insomnia I experience. I last consulted him a week ago, and he admitted uncertainty on how best to manage my case from here. Ultimately, I'm reaching out to find out if there’s a possibility that I might be dealing with long COVID or a similar condition. My pulmonologist seems to think it unlikely, especially since I did not contract COVID right before my symptoms began. However, through my own research, I’ve come across accounts of individuals developing long COVID symptoms months after their initial infection had resolved. I’m now contemplating whether my flu was, in fact, a milder COVID case that somehow triggered these issues following my exposure to silica dust, possibly sparking an immune response that reactivated long COVID. While I realize this may seem far-fetched, my medical team has largely exhausted their investigative options, and I’m exploring any alternative approaches myself. Since returning to my workouts and modifying my diet with intermittent fasting, I feel like there might be slight improvements in my breathing, but I’m unsure if it’s genuine progress or merely a result of the placebo effect. I yearn to regain control over my life. I would greatly appreciate any insights, advice, shared experiences, or even general comments on my situation.
Recovery Questions After Orbital Fracture Surgery: When Can I Vape, Engage in Sexual Activity, and Eat Regular Foods? (19M)
Greetings, I’m a 19-year-old male, measuring 192 cm and weighing 95 kg, who smokes regularly. I don't have any significant medical history. Recently, I underwent surgery for a blow-out orbital fracture four days ago. During the procedure, a dissolvable implant was inserted through my gum due to persistent double vision, which is gradually improving. My current state is quite good with little to no pain, but I’d like to ensure that I don’t do anything that might hinder my recovery. I have a few inquiries regarding my post-surgery care: 1. What is the appropriate timeline to safely start vaping again (nicotine)? 2. When is it advisable to resume masturbation or sexual activities without jeopardizing the position of the implant? 3. At what point can I eat regular foods again, such as sandwiches, pizza, or chocolate? I recognize that the stitches in my gums are designed to dissolve and that the implant will also gradually dissolve. I appreciate any advice provided! My goal is to ensure a smooth healing process without any setbacks.
