Understanding the Connection Between Anti-Psychotics and Inflammation in PVNS
During my college years, I received a diagnosis of Pigmented Villonodular Synovitis (PVNS) affecting my left hip. This condition had troubled me since adolescence. I experienced severe flare-ups that would render me unable to bear weight on my leg, necessitating the use of a cane. Fortunately, after a week, I would regain the ability to walk without assistance or pain. These episodes persisted intermittently throughout my twenties. At the age of 29, in 2021, I was diagnosed with an unspecified form of psychosis, for which I was prescribed 2 mg of Risperidone. I consider myself fortunate, as I haven’t faced a relapse of psychotic symptoms, apart from a brief period when I abruptly stopped taking Risperidone for a few months. Since resuming my medication in 2022, I’ve not experienced any further psychotic episodes. Interestingly, I have noticed that my left hip tends to attempt flare-ups on occasion, yet they tend to resolve by the following day. What could explain this connection? I find this relationship both perplexing and intriguing.

Your observations about the relationship between your anti-psychotic medication (Risperidone) and the flare-ups of Pigmented Villonodular Synovitis (PVNS) are indeed intriguing. Let’s explore this connection and what it might mean for your situation.
Main Points:
- Potential Interaction: While there is no direct known link between anti-psychotic medications like Risperidone and PVNS, medication can sometimes influence inflammation and pain perception.
- Inflammatory Response: Your PVNS itself is an inflammatory condition, and it's possible that fluctuations in your stress levels or overall mental health could indirectly impact its severity.
Explanation:
Risperidone is known to impact neurotransmitters in the brain, particularly dopamine and serotonin. Alterations in these neurotransmitters might influence how you perceive pain or respond to stress, which can exacerbate inflammatory conditions like PVNS. Moreover, stress can trigger inflammatory responses, potentially leading to flare-ups in conditions like yours.
The fact that your hip tends to flare-up but resolves quickly might indicate that these episodes are linked more to short-term stress or inflammation rather than a chronic worsening of your PVNS.
Next Steps:
-
Monitor Symptoms: Keep a detailed log of your hip symptoms, especially noting when flare-ups happen in relation to your mental state or stress levels. Track these patterns over time for better insights.
-
Manage Stress: Incorporate stress-reducing activities such as mindfulness, yoga, or gentle exercise. These can support both mental health and possibly help alleviate inflammation.
-
Consult with Health Professionals: While I won’t suggest seeking immediate consultations, if your hip symptoms or mental health change significantly, consider discussing these observations with your healthcare provider to explore adjustments in treatment if necessary.
-
Stay Active Safely: Ensure you are engaging in low-impact activities to keep your hip joint from becoming stiff and strengthen surrounding muscles, as tolerated.
Your experiences are valuable, and it's good to keep an eye on how different aspects of your health interact with each other. Feel free to share any patterns you notice or further questions as you continue to navigate your health journey.

Managing Seroma After Total Thyroidectomy
I’m a 41-year-old woman who doesn’t smoke and takes various medications, though they aren’t pertinent to my current health issue. On July 11, I underwent a total thyroidectomy due to potential cancer and significantly enlarged lobes. Unfortunately, I have since developed a persistently problematic seroma, which has required drainage from my doctor on two separate occasions. Despite the considerable amount of fluid being extracted, the seroma fills back up shortly after, typically within a few hours of leaving the medical office. This accumulation creates a tight sensation in my throat, leading to challenges with eating and swallowing. My doctor has been understanding and supportive throughout this ordeal, and I have an appointment scheduled with him on Monday. During this visit, I plan to discuss possible next steps, as the office drainage doesn't appear to provide lasting relief. I’m curious to hear about how others have resolved similar issues. Why does the fluid seem to return as soon as the wound closes? The tight feeling is quite uncomfortable. Currently, I have been alternating between heat and ice to alleviate some discomfort, but I’m still feeling quite miserable. I have yet to properly recover from surgery or adjust to life without a thyroid and I’m still awaiting pathology results, which is taking a toll on my mental well-being. Any advice or support would be greatly appreciated. Thank you for taking the time to read my post!
Exploring Causes of Lingering Oral Discomfort
Age: 25, Height: 5'0", Weight: 120 lbs. I've encountered a troubling situation that began approximately a month ago after I consumed an inexpensive margarita. This is an unusual occurrence for me, and my initial thought was that it might be an allergic reaction, but the symptoms have continued for a full month. I sought medical attention at an urgent care facility, where I was prescribed steroids and fluconazole, suspecting a possible case of oral thrush, but none of these treatments have proven effective. I experience significant sensitivity to stress, leading me to wonder if the discomfort in my mouth is a manifestation of stress or possibly a viral infection. Currently, I am using aloe vera mouth rinses, K12 probiotic lozenges, and adhering to a bland diet in hopes of finding relief. Unfortunately, my primary care physician isn’t available for an appointment until late July, and I am left feeling helpless. My greatest desire is to return to normal eating habits and regain my comfort while dining.
Experiencing Persistent Muscle Twitching and Occasional Tingling – Should I Be Concerned?
I am a 36-year-old female, standing at 5'9" and weighing 175 pounds. For the past eight months, I've been working as a scrub nurse. My current medications include albuterol, and I take various supplements such as B12, a multivitamin, magnesium, turmeric, biotin, and vitamin D. I avoid smoking and drinking, but I do use THC to help with sleep. For the last three weeks, I have had ongoing symptoms: - Continuous twitching in my left calf and foot, with occasional spasms in my left glute. The sensation feels akin to "wiggling worms" and often occurs in multiple locations simultaneously. Initially, I experienced a buzzing sensation in my leg and foot, reminiscent of a phone vibrating silently. - Occasionally, I feel mild tingling or pins and needles in my left foot, though there’s no associated numbness or weakness. - There’s no pain involved, but the buzzing and vibrating sensations are persistent. I do have a video capturing my calf activity, which I plan to share in the comments. Tests conducted so far include bloodwork checking CBC, electrolytes, B12, thyroid levels, and markers like ESR and CRP, all of which returned normal results. However, my iron levels were slightly low, likely linked to my vegan diet. To manage my symptoms, I have tried: - Taking 500 mg of magnesium daily. - Staying hydrated and replenishing electrolytes. - Wearing compression socks throughout my shifts (this has been ongoing for months). - Incorporating stretching and foam rolling into my routine. - Eliminating caffeine and alcohol from my diet. I have a few questions: 1. Could this still be benign fasciculation syndrome (BFS) considering the tingling sensations I experience? 2. Should I consult a neurologist or request an EMG exam at this point, or would it be better to wait? 3. Are there any additional tests or treatment options I should think about? As a nurse who spends the entire day on my feet, I do feel anxious about the possibility of ALS or MS, but I'm attempting to maintain a rational perspective in light of my health worries. In my recent visit to my doctor, she did not perform a physical examination but suggested I simply monitor the situation, attributing it to my prolonged standing. While she mentioned my B12 levels could be a factor because of my veganism, my recent blood tests showed normal levels.
Seeking Assistance for Migrating Lower Back Pain
**Age:** 22 **Gender:** Female **Height & Weight:** Approximately 5’3”, around 185 lbs **Medications:** Currently on Bactrim for a urinary tract infection I have been experiencing a burning, tight sensation in my lower back, particularly around my hips and buttocks. The discomfort shifts frequently from one side to the other, at times extending into my buttocks and down the back of my legs. It’s a constant ache that intensifies when I bend over, accompanied by a peculiar bruised or ticklish sensation when I apply pressure to the affected area. While the pain isn't sharp, it is certainly bothersome. Interestingly, I find that standing or walking alleviates the pain somewhat, whereas sitting or resting tends to worsen it. I did take Tylenol, which provided minor relief. Recently, I have been quite active, particularly while at the beach, but I didn't engage in any heavy exercise or sustain an injury. On Monday, I underwent a CT scan of my abdomen and pelvis to exclude the possibility of a kidney infection and other potential issues. Fortunately, the results were normal, confirming that my kidneys are fine. I continue to use Bactrim to complete my treatment for the UTI. Now, I'm left wondering if this discomfort could be related to sciatica, a pinched nerve, or possibly piriformis syndrome. I've never experienced back pain like this before, and it has me feeling anxious. I would appreciate any insights: Does this seem to be related to nerve issues? Should I consider making an appointment with a healthcare professional, or is it advisable to wait it out? In the meantime, are there any home remedies—such as stretching, resting, applying ice or heat— that you would recommend? Thank you for your help! 💛
Unexplained Sweet Smell in My Child's Urine
My son, age 5, is an American Indian and Hispanic child who is autistic. He had comprehensive genetic testing approximately 18 months ago. He also has a history of asthma and is currently on Symbicort, along with a rescue inhaler that he uses when necessary. Recently, while tidying up his room, I detected a sweet scent emanating from his bedding. Initially, I attributed it to a possible treat he might have snuck in without my knowledge, so I merely checked for any items that could attract pests. Today, I decided to change his mattress cover and discovered some spots that appeared to be urine. Upon closer inspection, I noticed that the bedding had that same unusual sweet aroma. After giving him a shower, I checked his pull-up and was alarmed to find it also had a sweet smell, quite unlike typical urine. This situation is quite confusing for me—should I wait until Monday to contact his pediatrician, or is there an immediate action I should take regarding these concerning odors?
