Experiencing Sudden Weakness in the Arm Due to Spinal Cord Compression?
I am a 41-year-old female, weighing 145 pounds and standing 5 feet 5 inches tall. My medical history includes ankylosing spondylitis, an unspecified myositis-like condition, severe bilateral carpal tunnel syndrome, and hypertension. Current medications consist of Humira, rosuvastatin, Tylenol, and Advil. A recent MRI revealed mild compressions at the C4-5 and C5-6 levels of my spinal cord, although there were no indications of abnormal signals. Upon waking this morning, I found myself completely unable to move my left shoulder down to my elbow. Attempts to raise my shoulder toward my ear or to lift my hand yielded only minimal movement, devoid of any pain or tingling sensations, just an overwhelming sense of weakness. Interestingly, I could still open and close my hand without difficulty. After approximately 20 minutes, movement in my shoulder returned to a near-normal state, but even now, six hours later, my arm still feels notably heavy. Raising it above my head requires significantly more effort than usual. Given the absence of pain, I suspect that I may have slept in a position that exacerbated the pressure on my spinal cord compression. Should I seek medical attention, or is this just a peculiar occurrence related to my body?

Your experience with sudden weakness in your arm, especially in the context of spinal cord compression and your existing medical conditions, is concerning. While the transient nature of your symptoms (quick recovery in movement) is encouraging, they warrant careful consideration.
Explanation:
Spinal cord compression can lead to neurological symptoms, including weakness, which is often a signal that the spinal cord is being affected. In your case, the sudden weakness that resolved relatively quickly could suggest temporary nerve compression, possibly exacerbated by your sleeping position or muscle relaxation during sleep. However, the presence of existing compression at the C4-5 and C5-6 levels, along with your medical history, suggests the need for caution.
Next Steps:
-
Monitor Symptoms: Keep track of any recurring weakness, changes in sensation, or new symptoms. Pay attention to whether this weakness occurs after specific activities or positions.
-
Modify Sleeping Position: Be mindful of your sleeping posture. Use supportive pillows to ensure your neck and spine are aligned and avoid positions that may aggravate your spinal cord.
-
Limit Strain: During the following days, avoid heavy lifting or straining activities that might put additional pressure on your neck and back.
-
Gentle Stretching: Engage in light neck and shoulder stretches to help relieve tension, but avoid any movements that cause discomfort or exacerbate weakness.
-
Consider Seeking Medical Attention: Given your health history and the recent symptoms, it may be wise to reach out to a healthcare provider for further evaluation, especially if the weakness recurs or worsens.
Ensuring that you take care of your spinal health is essential, and while this may seem like a singular incident, your underlying conditions make it prudent to be vigilant. Please feel free to ask more if you have additional concerns or need clarification on any points.

Blood in Urine: Seeking Guidance
A 20-year-old female weighing 140 pounds has not been taking any medications or supplements, and has no prior or current medical conditions. Her menstrual cycle last occurred two weeks ago. While at work, she observed blood in her urine, which appeared light red but darker than pink. Accompanying this symptom, she has experienced some abdominal discomfort. Notably, there was no evidence of blood on her underwear, only when she urinated. Additionally, she felt a moment of lightheadedness upon noticing the blood, which has since subsided; she attributes this feeling to her anxiety about the potential seriousness of the situation. Given these symptoms, what could be the likely cause? She is uncertain whether to visit the emergency room or to wait until urgent care is available tomorrow for a consultation. As she recently relocated and does not have a primary care physician yet, her anxiety is heightened.
Exploring Endolymphatic Hydrops: Could This Be My Condition?
34 years old / Female Current weight: 165 lbs Navigating the challenges of motherhood In early December 2025, I caught a cold. By mid-December, my right ear felt blocked, but I attributed it to the cold virus. As New Year approached, I experienced another cold, which coincided with an onset of ringing in my ears. Disturbingly, sounds started to seem altered from the affected ear, accompanied by a persistent fullness in that area. Additionally, I noticed twitching of my eye and swelling in the salivary gland on the same side. My primary care physician prescribed a decongestant and Flonase; however, because I am currently breastfeeding, I hesitated to take the medications as directed. On January 27, I was evaluated by an ear, nose, and throat specialist, who requested a hearing assessment the following day. The results indicated that I had sensorineural hearing loss affecting my low-frequency hearing range (250 Hz to 500 Hz). The doctor prescribed a steroid with the hope of addressing the issue promptly. Now on day 10 of steroid treatment, I have experienced significant relief. Remarkably, I've noticed a substantial amount of thick, putty-like mucus clearing from my nasal passages. The pressure in my ear has subsided, and sounds are returning to normal, though I still perceive a slight ringing — possibly just a touch of hearing loss remains. What concerns me is whether ongoing sinus congestion could be the root of these symptoms or if I might genuinely be dealing with endolymphatic hydrops. Notably, I have not experienced any episodes of dizziness. In the evenings, I tend to feel considerable pressure building on the right side of my head, almost as if my sinuses are becoming blocked once more. I would greatly appreciate any insights or advice on this matter, as I find myself in a state of uncertainty regarding my condition.
Experiencing Occasional Hematuria: Seeking Guidance
Greetings, medical professionals. I appreciate your assistance with the following situation. **Patient Overview:** - **Age:** 47 - **Gender:** Male - **Height:** 6 feet - **Weight:** 202 pounds **Symptoms Overview:** Approximately three months ago, I began to observe small traces of blood in my urine. It's a minimal amount, usually just a couple of drops occurring at the end of urination. I do not suffer from any pain, fever, chills, or urinary difficulties. Initially, I suspected that this could be linked to kidney stones or exercise-induced hematuria, as I maintain a rigorous exercise routine spanning two hours daily, seven days a week. My workouts alternate between strength training 3-4 times a week and cardio exercises, including rowing, treadmill use, the elliptical, stair climbing, and jump rope. After several weeks, I also observed tiny tissue-like fragments in my urine, prompting me to consult a doctor, as I suspected a urinary tract infection. Although I have an enlarged prostate, my physician considered it a benign issue, attributing the swelling to the potential chain reaction of a UTI leading to bladder infection and subsequently causing prostate inflammation. **Diagnostic Tests and Outcomes:** I underwent a comprehensive metabolic panel, which included tests for glucose, BUN, creatinine, and various electrolytes. All results fell within normal ranges, with the exception of a low BUN/creatinine ratio (8). Additionally, I received a Creatine Kinase (CPK) test, which returned normal results. A complete blood count (CBC) with differential was conducted, showing all parameters, including WBC, RBC, and hemoglobin, to be normal. Urinalysis reflected negative findings for GLU, BLO, NIT, and LEU. However, it indicated a small amount of bilirubin, a ketone level of 15, a specific gravity of 1.025, a pH of 5.5, and a protein level at 30. Uric acid levels were 8.1, within normal limits, though an inflammatory marker was mildly elevated. A sedimentation rate (Westergren) displayed a slight elevation at 19 (normal range is up to 15). A CT scan of the abdomen and pelvis with contrast yielded several findings: - **Lung Bases:** A few small pulmonary micronodules were noted, but otherwise clear. - **Liver, Spleen, and Pancreas:** All appeared normal without lesions. - **Kidneys:** Normal with no stones or masses. - **GI Tract:** The stomach was mildly distended, but otherwise normal with stool presence noted in the colon. - **Pelvis and Vascular Structures:** Solid organs and vessels appeared normal. - **Other Findings:** Prominent inguinal lymph nodes were potentially reactive, alongside a small left inguinal hernia. **Follow-Up Treatment:** Following these evaluations, my physician prescribed sulfamethoxazole for a duration of 28 days. I adhered to the regimen fully, and while undergoing treatment, all symptoms subsided completely. However, this occurred about a month ago, concluding in late December. **Current Situation:** This evening, after my workout, I noticed the return of blood traces in my urine. While I do not experience pain, I have difficulty with bowel movements, feeling persistently constipated regardless of food intake. This change coincided with a mild tearing sensation during exercise on the adductor machine. Additionally, I have developed a reddish rash on both arms, which had resolved during the antibiotic treatment but has now reappeared. Previously, this rash was effectively treated with prednisone, leaving me unsure if this is connected to my earlier symptoms. **Concerns:** I worry that standard medical tests might overlook a significant issue affecting my prostate, colon, or urinary system. My insurance policy does not cover colonoscopy or prostate evaluation, and I have been advised to consider these procedures, though they would cost nearly $7,000 out of pocket. While I understand the necessity of these assessments if needed, I prefer to seek a second opinion before committing to such expenses. It's important to note that there is a family history of cancer, primarily lung cancer. I welcome any advice or insight into my case and will provide any additional details you may require.
Unexpected Head Pain During Dance Moves
This may seem humorous, yet I'm genuinely interested in uncovering the cause of this peculiar experience. I’m a 34-year-old female. A few months back, hoping to elevate my mood and get my body moving away from the grip of depression, I decided to play some music and dance in my living room. In a moment of misguided enthusiasm, I attempted to twerk. It's worth noting that I have a long history of lower back discomfort, I've never attempted to twerk before, and I lack the rhythm, flexibility, or skills typical of proficient dancers. As I embarked on my very first serious twerk attempt, a sudden jolt of agony shot through my forehead, nearly causing me to lose consciousness. It felt like being struck with a hammer. I was momentarily blinded by the pain, convinced I might have suffered an aneurysm or something equally serious. This intense sensation only lasted for about a minute, during which I dramatically considered that I might be the first individual to perish from twerking. You might think it was just a case of me bumping my head while trying to dance away my sadness; however, I assure you that this wasn’t the case. Just as abruptly as the pain struck, it dissipated. In that moment, I promised myself to never attempt twerking again. Fast forward to today, and I experienced a similar incident again—not the twerking, but the sudden stabbing pain in my skull. I was engaged in some back stretches, particularly the cat-cow pose, and during the cow portion, I once more felt an intense sharp pain in the center of my forehead, just above my right eye. Stars filled my vision, and everything seemed slightly distorted. This sensation vanished within seconds, leaving me puzzled. What is causing this reaction? How do my forehead and lower back relate in this context? It's baffling! I genuinely seek any insights that might help explain this mysterious phenomenon.
14-Year-Old Male with Cough and Rash Symptoms
My 14-year-old son, who stands at 5 feet 3 inches tall and weighs 149 pounds, has been experiencing persistent cough and cold-like symptoms for slightly over a week. He stayed home from school on January 30 and February 3 as he was feeling unwell, but aside from that, he has managed to attend school. The predominant issue has been his cough. Initially, he had a runny nose for a couple of days, but that symptom has since resolved. He has not complained about a sore throat or experienced any fever. This afternoon, he reported developing a rash with red spots. He mentioned that it itches a little, but it's not uncomfortable, and he does not feel any pain. The rash is primarily located on his abdomen and chest, with some patches on his legs and a little on his arms, but there are no spots on his back. I checked his temperature, which was recorded at 99.4°F. He is fully vaccinated according to the standard vaccination schedule recommended by pediatricians in the United States. Our residence is near Vancouver, WA, in case that information is pertinent. Additionally, we have not changed any laundry or personal care products recently. What could this condition possibly indicate?
