Unexplained Hamstring Muscle Spasms

8/28/2025, 1:55:42 PMMale25-34

I am a 29-year-old female with a weight of 51 kg and a height of 167 cm, and I do not have any significant health issues. Recently, for over a month, I have been dealing with uncomfortable spasms in the muscles at the back of both thighs. To clarify, this isn’t the same as a charley horse. My physical activities are limited to occasional yoga, swimming, and dancing—I do not regularly go to the gym, and I can't attribute these spasms to any injuries or physical strains. It all began after I attended a concert where I stood in line for two hours. Initially, I thought the discomfort might be due to fatigue, but as time went on, the spasms persisted. These episodes consist of quick, sharp pains that can affect either leg, prompting me to massage the affected area or sit down. They do not disturb my sleep, nor do they arise during exercise; rather, they tend to occur after sitting for a while or upon getting out of bed in the morning, specifically when I am standing still. Unlike cramps—which I am quite familiar with as they typically affect me at night or occasionally during stretching—these spasms feel different. In an effort to alleviate the situation, I have been increasing my physical activity and focusing on hamstring stretches, yet I have seen no improvement. I consulted a neurologist about my concerns, but the examination yielded no evidence of neurological issues. Additionally, blood tests showed normal levels of electrolytes and a creatine kinase level of 40. Although I do have a herniated disc located higher in my spine (D12-L1), it doesn’t seem to be responsible for my symptoms, particularly since I do not experience any back pain. I am seeking advice on how to proceed, as these sporadic but disruptive spasms continue to affect my daily life, especially in my work as a photographer.

It sounds like you're experiencing persistent muscle spasms in your hamstrings that are affecting your daily life, and it's great that you've already consulted a neurologist and have had blood tests done. Your symptoms may be related to muscle fatigue, posture, or even the impact of prolonged standing, especially since they followed a lengthy time spent standing at a concert. Here’s how you can address this situation:

Explanation

Muscle spasms can occur due to a variety of factors, including muscle fatigue, dehydration, or minor nerve issues. Given that the spasms you experience seem to be linked with periods of rest, especially after sitting or when getting out of bed, it could suggest that your muscles are stiffening or are not receiving adequate blood flow after inactivity.

Priority Next Steps

  1. Hydration: Ensure you are drinking enough fluids throughout the day. Dehydration can lead to muscle spasms, even if your electrolyte levels are normal.

  2. Stretching Routine: While you’ve started incorporating hamstring stretches, consider adding dynamic stretching and a warm-up before going into static stretches. Tightness may still persist if only static stretches are performed.

  3. Strengthening Exercises: Incorporate low-impact strengthening exercises focusing on your core and lower body. Strengthening these areas can help stabilize your muscles and support your spine better.

  4. Posture Awareness: Be mindful of your posture, especially when sitting or standing for extended periods. Consider using supportive seating and take regular breaks to walk around and stretch during long work sessions.

  5. Heat Therapy: Apply a warm compress or take a warm bath to relax the muscles before bed or after a long day. Heat can help in easing tightness and reducing spasms.

  6. Consult a Physical Therapist: If you haven’t already, working with a physical therapist can provide personalized exercises and stretches tailored to your symptoms and movement patterns.

  7. Monitor Symptoms: Keep track of when these spasms occur, their duration, and any triggers. This information can be valuable in understanding patterns and addressing root causes.

If the spasms persist or worsen despite these interventions, it may be worthwhile to seek further evaluation of your spinal health, considering your herniated disc, or explore other potential causes with a healthcare provider.

I hope this helps you find some relief. Remember you can take it step by step; gradual changes in your routine can make a significant difference over time.

Managing Early Appendicitis: Antibiotics vs. Surgery

I’m a 21-year-old who recently had a CT scan revealing mild inflammation in my appendix and lymph nodes. My doctor informed me that surgery might not be necessary if the antibiotics effectively alleviate my discomfort by tomorrow. However, I can’t shake my fears about a potential recurrence of the inflammation. The thought of going through a post-surgery recovery terrifies me, so I really want to steer clear of that option. Has anyone opted for antibiotics rather than surgical intervention? What was your experience like?

Concerns Over My Partner's Persistent Pain and Resistance to Seek Medical Help

I’m facing a worrying situation with my partner, a 40-year-old man who stands 6 feet 1 inch tall and weighs approximately 19 stone. Here's a brief overview of his medical background: Twenty years ago, he experienced two instances of deep vein thrombosis (DVT) in his left shoulder. Following the second incident, doctors discovered an abnormal growth of a rib that was pressing against a vein, which was the cause of those DVTs. More recently, he dealt with a blood clot in his calf last year. Fortunately, that was successfully treated, and he returned to his normal health. Although he was advised to continue taking apixaban for the long term, he has, unfortunately, chosen not to follow through with this guidance. He also has a history of elevated blood pressure. For the past couple of days, he has been experiencing two concerning symptoms that emerged simultaneously: a persistent cough with no accompanying cold or flu signs, and a severe pain located on the right side of his torso. He describes this discomfort as being mostly in his stomach yet extending slightly to his back. I would pinpoint the troubled area as the lower part of his ribs along the side of his body. It's unusual for him to express discomfort or complain about his health, so his recent grievances signal to me that the pain is likely quite significant. Despite my repeated suggestions for him to visit a doctor, he insists that he may have simply pulled a muscle. To manage the pain, he's been applying an ibuprofen cream (voltarol) and taking naproxen, but neither seems to provide relief. What might be the underlying issue here? I hope that some medical professionals who see this post can offer their insights, which might persuade him to consider making a doctor’s appointment. I’m open to providing any additional information you might require for a more informed perspective. Thank you for your help!

Struggling with Bleeding and Pain Since Christmas

I'm a 27-year-old woman from the UK, and I've reached a point of exasperation. I'm reaching out because I hope someone can provide insight or guidance on what I should discuss with my doctors. Please excuse any grammar or spelling errors as I have dyslexia. I've been diagnosed with endometriosis and underwent surgery in 2022 for confirmation of that diagnosis. On December 15th, I had my birth control implant removed after nearly two years. During that period, I experienced severe menstrual cramps and PMS. My GP started me on Drospirenone 3mg and Estetrol 14.2mg COCP in October to alleviate these symptoms and suppress my periods, which provided some relief. Prior to this situation, I occasionally dealt with flare-ups that typically lasted a few days or up to a week. To help manage the discomfort, I have been prescribed Duloxetine at a dosage of 90mg. I had an ultrasound earlier this summer, and the results came back normal. Currently, I am awaiting an MRI. Last year, my smear test results were also clear. After the removal of my implant in December, I began bleeding on Christmas Eve. Initially, I could manage with just a panty liner, but over the next few weeks, the bleeding intensified, requiring the use of pads due to increased blood flow and blood clots. Given my history with endometriosis, pain isn't unfamiliar to me; my average pain level is around a 4, but it has recently escalated to 7 or 8. In the past couple of weeks, the discomfort has worsened. My job demands physical activity, and bending over now causes pain in my back and legs. Additionally, I experience discomfort when my bladder fills, and urination is painful, although it doesn't feel like a urinary tract infection. I've also been waking up at night to use the restroom. My doctor performed a urine dip test that showed no signs of infection, though there was blood in my urine, which he indicated was to be expected. Recently, my GP prescribed Tranexamic acid 500mg and Mefenamic acid 500mg, which helped with the blood clots, but I'm still experiencing bleeding and significant pain. I've been diligent about taking my medication, treating it like a strict regimen. I returned to the GP, who referred me for another ultrasound and advised me to go to A&E if the pain worsens. I've been resting as much as possible while still trying to maintain some level of activity, but it hasn't provided much relief. Any assistance or advice would be immensely appreciated! Thank you!

Experiencing Unusual Sensitivity to Paracetamol

Hello, Reddit community! I'm a newcomer here, so please bear with me as I navigate this platform as well as the rules. I appreciate your understanding regarding my writing skills. I find myself in a situation that lacks sufficient information online, and I'm reaching out for insights from others. Currently, I have reasons to believe that I might be experiencing a unique sensitivity to paracetamol, and I’d like to share my timeline regarding this matter. Throughout my life, I generally had no issues with paracetamol. I used various brands multiple times and felt fine. However, starting in the fourth grade, I began to experience difficulties with it. My initial problems were respiratory-related, but soon they also affected my gastrointestinal system. I haven't had any formal testing yet, but I can safely use other pain relievers like NSAIDs without any adverse effects. Initially, I tolerated paracetamol relatively well; my early symptoms seemed like common side effects. Unfortunately, it escalated to severe reactions, including vomiting, tightening of the throat, blood in my mucus, and shortness of breath. In my confusion, I thought limiting my dosage could help, which it did temporarily, but eventually even the reduced amounts failed to be effective. I experimented with syrup formulations that contain less paracetamol or where it isn't the primary ingredient, and found those to be more manageable. Recently, however, even those have become problematic, making it necessary for me to seek alternatives to paracetamol, as it has become increasingly intolerable. Through my research, I discovered that such reactions often stem from cross-sensitivity to other medications or from preexisting respiratory conditions. I lack a history of asthma or other respiratory issues, so I’m inclined to dismiss that possibility, although I remain uncertain. Moreover, I have no known allergies, which adds to my confusion since my reactions only occur with this one particular medication while all others seem fine. It is difficult for me to process this change, especially since I used to have no issues with paracetamol. It is widely available and generally considered safe, so I struggle to understand the source of my suffering. Many people insist that these reactions are normal side effects, leading me to question whether I am overreacting. The immediacy of my reactions intensifies my concern; I don’t even need to swallow the medication completely before I notice my throat constricting, increased mucus production, and shortly thereafter, some blood in my mucus along with persistent coughing. This pattern has become consistent, whereas it used to depend on the dosage. Now, regardless of how much I take, the same symptoms occur. I’ve tried to dismiss it, not wanting to worry my parents or seek medical attention for a dosage safety test, fearing I’ve already pushed my body too much. However, I am considering discussing my concerns with my mother since she is increasingly worried about my use of this medication. I’m not seeking a diagnosis or medical advice—I understand I should probably consult a professional. I’m just interested in knowing if anyone else has faced similar experiences, as the confusion grows. What I once assumed were normal side effects now seem to signify something more concerning.
