Am I Experiencing Rhabdomyolysis?
I'm a 19-year-old female and recently engaged in a treadmill session for about 20-25 minutes, set at an incline of 10 and a speed of 3. Afterwards, I reduced both the incline and speed, walking for another 10-15 minutes. Additionally, I completed a brief leg workout without weights, marking my return to exercise after some time away from college. I've been less active at home compared to my usual campus routine. Today, approximately 13 hours ago, I pushed myself more during my workout than I did on Monday. Throughout the day, I've been feeling a noticeable weakness in my thighs. While I can still manage to climb stairs, they do feel less strong than usual. Earlier, I urinated, and although the color wasn’t brown, it was a darker shade of yellow, which suggests I might be a bit dehydrated. I'm feeling quite anxious about the possibility of rhabdomyolysis and am unsure of the best course of action. To remedy the situation, I'm currently consuming plenty of water mixed with liquid IV to replenish my hydration and encourage urination. I'm open to sharing a photo of my urine color through direct messages if needed. To be cautious, I’ve decided to refrain from any workouts for a full week. When I resume exercising, I plan to take it extremely easy to avoid any further issues. 😅

It sounds like you're experiencing some muscle fatigue and dehydration after your recent return to exercise, which is quite common after a break. However, your feelings of anxiety about rhabdomyolysis are valid, especially given your symptoms. Let's break this down:
-
Understanding Rhabdomyolysis: This condition occurs when muscle tissue breaks down and releases protein (myoglobin) into the bloodstream, which can lead to kidney damage. Common symptoms include severe muscle pain, weakness, swelling, and dark urine. While you're not experiencing brown urine, the darker shade of yellow may indicate some degree of dehydration, which is something you are already addressing by increasing your fluid intake.
-
Your Symptoms: The weakness in your thighs and darker urine could suggest mild exertion-related muscle soreness, particularly after an intense workout following a period of inactivity. This is often referred to as delayed-onset muscle soreness (DOMS).
Next Steps:
Prioritize Hydration and Recovery:
- Continue Hydrating: Keep drinking water throughout the day. Your use of liquid IV is helpful for electrolyte replenishment.
- Rest: Allow your muscles time to recover by avoiding intense exercise for at least a week, which you already planned. Gentle stretching or light activity like walking may maintain circulation without overexertion.
Monitor Your Symptoms:
- Check Urine Color: Keep an eye on your urine color. If it becomes significantly darker or if you experience new symptoms such as extreme muscle pain, swelling, or decreased urine output, it could indicate a more serious issue.
- Watch for Other Signs: Be alert to symptoms like severe fatigue, nausea, confusion, or swelling in your muscle areas.
Gradually Resume Exercise:
- When you feel ready to return to exercise, start with low-intensity activities and gradually increase the intensity. Aim for shorter sessions and listen to your body’s signals.
Reassurance and Support:
- It's completely normal to feel cautious after pushing your body, especially if you haven't been as active recently. Taking it slow and ensuring proper hydration will help you recover well. If anxiety about your symptoms persists or worsens, seeking guidance from a healthcare professional would be wise, but monitoring yourself with these steps should provide clarity and comfort.

27 Years Old – A Life Without Erections
At 27 years of age, I've never experienced an erection. My health profile includes several factors that often lead to erectile difficulties. These are: - Depression - Overweight - High Blood Pressure - Diabetes I’ve never encountered instances of ‘morning glory’ or had any nocturnal emissions. I’ve attempted to gauge whether I experience erections during sleep, but the tests consistently indicate otherwise. While I can achieve some level of blood flow to the penis, it is merely an increase in size rather than a firm erection. Ejaculation is still possible for me, although I’ve never experienced the sensation of orgasm. I don’t believe any of my existing health conditions directly contribute to this absence of erections, as I didn’t always have these health issues but still faced this challenge. In my research, I haven’t stumbled upon any other men who’ve shared a similar experience of never having an erection, only those who mention having them sporadically. I am keen to understand what sets me apart from others and what the potential long-term effects of this situation might be.
Experiencing Complications After Corticosteroid Infiltration
Hello everyone, my name is M, and I’m a 21-year-old sharing my story about complications I faced after a corticosteroid infiltration that took place over a year ago on May 28, 2025. Due to persistent discomfort stemming from a pinched disc at levels L4 and L5, I underwent this procedure after experiencing pain during activities like walking, sitting, and certain sports, as well as ongoing digestive issues. After discussing my situation with my physician, I opted for an MRI which revealed a minor herniation alongside degenerative disc issues. Unaware of potential complications, I went ahead with the infiltration, which at first seemed uneventful. However, within days, I began to experience alarming symptoms such as balance loss, position-dependent headaches, and an overwhelming sense of faintness. Physical sensations felt unusual, and overall bodily weakness became pronounced, particularly in my lower limbs. As time passed, it felt like my physical strength was rapidly diminishing; I went from weighing 70 kg of lean muscle to just 60 kg, essentially losing all of my physical strength. My masculine traits have notably faded—my broad shoulders shrank, and I noticed changes in my libido and physical appearance. Additionally, I began experiencing muscle spasms in various areas and discomfort in my hands and arms, even impacting my previously unaffected right leg. Currently, I weigh 59 kg and find it increasingly difficult to walk or maintain a posture without feeling significant pain. I spend most of my time lying down, where discomfort persists. Disturbingly, I’ve developed noticeable scoliosis, and my legs tremble from weakness. Nerve pain has become intolerable, stemming from what seems to be issues with the sciatic nerve. I feel utterly overwhelmed and let down, as my condition deteriorates week by week. Before undergoing the infiltration, my testosterone levels were tested at 15.46 nmol/l at 9 a.m., which was within the normal range and gave me assurance. However, my recent tests show a drastic decrease to 11.23 nmol/l, with my free testosterone dropping below normal at 22.1 pmol/l. Despite several visits to the emergency room where I detailed these symptoms, I was frequently sent home due to unremarkable blood test results. Medical staff suggested that I may have psychological concerns, emphasizing that it might all be in my head. Now, with the recent hormonal test results, I finally have solid evidence to reflect the significant decline in my testosterone levels. I apologize for the lengthy message, but I felt it necessary to share my experiences. If anyone is facing a similar situation or would like to discuss this further, please reach out. Thank you all for your understanding and support.
Rehabilitation for Forearm Surgery
Earlier this year, specifically in February, I underwent a surgical procedure to address compartment syndrome affecting both of my forearms. Recently, while rowing, I experienced pain reminiscent of the symptoms I faced prior to the operation. Just last week, I participated in a race, marking the first time I've competed since my recovery began, and I've noticed some of those earlier issues resurfacing. Is it typical for individuals who have had this type of surgery to encounter similar complications afterwards? I had anticipated a complete resolution of my symptoms post-surgery, but perhaps I may have rushed through my rehabilitation process. Given this situation, I’m curious about the recommended steps I should take moving forward. Should I prepare for the possibility of needing another procedure? Additionally, is there an immediate need for a consultation with my doctor? To provide some context, I am a 23-year-old male, otherwise in good health, standing 5’10" and weighing 78 kg. The discomfort I’m experiencing is present in both forearms.
Experiencing Bruises and High MCV: Seeking Guidance for Next Steps
Hello everyone — I'm a 34-year-old female and was diagnosed with Lyme disease approximately a decade ago through a spinal tap. Recently, I’ve noticed a decline in my health and feel as though my concerns are not being taken seriously. **Symptoms I’m Experiencing:** - Recurrent small bruises on my arms and legs, along with bleeding gums and occasional nosebleeds. - Presence of petechiae and nails that tend to break easily. - Symptoms such as numbness, cognitive fog, and heightened anxiety. - Digestive issues, including bloating, alternating constipation and diarrhea, plus unexplained weight gain. **Recent Laboratory Findings:** - MCV: 100 (elevated) - CO₂: 18 (decreased) - High cholesterol and LDL levels - Other tests including CBC, platelets, thyroid, liver, and kidney assessments are within normal ranges. **Next Steps:** I’ve requested additional tests for B12, folate, clotting factors, ANA, and iron levels but have yet to receive any results. Do you think these issues could stem from a vitamin shortage, an autoimmune condition, or perhaps complications arising from Lyme disease? Should I consider requesting a consultation with a hematologist or a neurologist? I would truly appreciate any insights or similar experiences you could share. Thank you so much! 💛
Comparing Loose Skin After Different Weight Loss Approaches
Consider the following case studies regarding weight reduction and its consequences on skin elasticity: In the first scenario, an individual sheds 120 pounds over the course of a single year, subsequently maintaining that weight for an additional year, achieving what is now their target weight. In the second scenario, the same individual manages to lose the same amount of weight but spreads the process over two years, achieving a more gradual decline. Now, the question arises: how does the condition of loose skin differ between these two individuals after a period of two years? Is it possible that the person from Scenario A, having undergone a rapid weight loss, experiences more loose skin that does not tighten back compared to the individual from Scenario B? Or is the single year of stable weight sufficient for skin recovery, resulting in comparable skin tightness for both?
