Calf Muscle Biopsy Report - Minimal Discomfort the Next Day
Greetings, I'm a 30-year-old male, standing at 5 feet 11 inches, weighing 190 pounds. Yesterday, I underwent a muscle biopsy on my right calf. The procedure was necessitated due to suspicions of Myositis, which were hinted at by an MRI. Additionally, I have an MRI planned for my lower back to exclude any potential nerve complications, as my EMG test yielded unexpected results. The incision measures approximately three inches and has resulted in some noticeable bruising. Surprisingly, I experience little to no discomfort unless I balance on one leg, and even then, the sensation is very mild. Is this typically what one should expect? I had been advised to prepare for significant pain in the initial days, and although the wound appears rather alarming, the absence of pain is concerning. I worry that if there is indeed a nerve issue, I may inadvertently injure myself due to my body not signaling discomfort as it normally would.

It's encouraging to hear that you're experiencing minimal discomfort after your calf muscle biopsy. This can be a normal response, especially considering individual pain thresholds and the specifics of the procedure. Let’s break down what you need to know and do next.
Key Points:
- Minimal Discomfort is Common: It's not unusual to have little to no pain after a muscle biopsy, especially when the procedure is performed under local anesthesia. Individual pain tolerances vary significantly.
- Monitor for Changes: While lack of pain can be concerning, it's important to focus on how your body feels moving forward, particularly given your ongoing concerns about potential nerve issues.
Explanation:
A muscle biopsy involves taking a small sample of muscle tissue, and many patients report moderate to mild discomfort afterward, particularly if the procedure was straightforward. Your low level of pain may be due to individual differences or the specific nature of your biopsy. The bruising is expected as it is a natural response to the skin being punctured.
Recommended Next Steps:
- Observe Your Symptoms: Continue monitoring the area for any signs of increased swelling, redness, excessive pain, or discharge, as these could indicate complications.
- Avoid Strain: Since balancing on one leg causes mild discomfort, it is wise to avoid activities that stress your calf muscle until you've fully healed. This will help prevent potential injury.
- Communicate Changes: If you notice any significant changes, such as increasing pain or loss of function, or if your upcoming MRI reveals nerve-related issues, consider bringing these up with your healthcare provider.
- Follow Up on MRI Results: Pay attention to the results of your next MRI as this could provide important context for any existing concerns regarding nerve issues.
- Pain Management: If necessary, you can use over-the-counter pain relief, like acetaminophen or ibuprofen, as directed, especially if you start to experience discomfort that is more than mild.
Your concerns about not feeling pain are understandable given the context of your medical history. Take it one step at a time—prioritize rest, listen to your body, and don't hesitate to reach out if you feel something is off. Stay positive, and make sure to follow up on the findings from your MRI as it will give you a clearer picture of what’s happening.

Concerns Over Possible Colorectal Cancer at 17
I want to share my experience as a 17-year-old who suspects I might have colorectal cancer. Lately, I've been dealing with health issues that include irregular bowel movements, specifically alternating between diarrhea and constipation, with a recent trend leaning toward constipation. Additionally, I feel a persistent, uncomfortable sensation as if my rectum is never completely empty. This discomfort extends to the lower abdominal area, making me feel like I haven't fully evacuated my bowels. At times, I experience abdominal pain, which varies in intensity, and I had a particularly rough week last June. After this troubling period, around the 25th, I ended up at the pediatric hospital, voicing my concerns about the possibility of having colorectal cancer. Of course, I had done my own research online, which only intensified my fears. I couldn’t shake the constant anxiety and began obsessing over cancer-related testimonials I'd watched. During my visit, the doctor assured me that at my age, it was highly improbable to have colorectal cancer. Instead, he prescribed laxatives. While my stomach discomfort slightly improved, the feeling of fullness and urgency in my rectum persisted, even after having several bowel movements. After returning to the doctor, I had the most uncomfortable experience of my life: a rectal examination. Following this, I underwent an abdominal ultrasound on July 18. During the ultrasound, I expressed my ongoing worries about colorectal cancer, but the technician laughed, reiterating that it was virtually impossible for someone my age. The ultrasound results showed nothing of concern, although I later learned that this type of scan doesn’t adequately assess the rectum and only provides limited views of the colon. Days turned into weeks, and for a period of three weeks, I felt relatively fine—no discomfort, pain, or abnormal bowel habits. I believed I was finally in the clear. However, just five days ago, the uncomfortable sensations returned. Though the abdominal pain was generally minimal, I once again struggled with that incessant rectal discomfort, which, while not overly painful, was deeply irritating. I felt overwhelmed, especially as my fears surrounding cancer reignited, compounded by the recurring discomfort and sporadic abdominal pain. It's worth mentioning that there's a history of irritable bowel syndrome in my family, though I have not seen any cases of colorectal cancer. While I’ve had instances of alternating bowel habits since I was about 13, the recent onset of pain and discomfort leads me to worry more about cancer. I have not noticed any blood in my stool, but this situation continues to disturb me. At times, I feel dismissed by the medical professionals, which raises my doubts about ever getting a colonoscopy. I apologize for the lengthy post, but I felt the need to express my thoughts. Thank you to anyone who took the time to read this. I hope you all are well and take care out there.
Understanding Calcified Lymph Nodes
Greetings, I'm a 21-year-old female, and recently underwent an ultrasound examination of my breasts. The doctor identified calcified lymph nodes in both armpits. However, I was reassured and informed that there was no cause for concern, attributing it to a prior infection. Should I pursue this matter further? I understand that such calcification can sometimes indicate cancer, though typically this is linked to more advanced stages of the disease, such as stage 4. I believe if I were facing a severe illness, I would likely be experiencing some noticeable symptoms. Nevertheless, what course of action would you recommend? Additional context: I have a diagnosed fibroadema which I'm currently keeping an eye on. I do smoke and consume alcohol occasionally, but overall, my health is good.
What Could These Growths in My Mouth Indicate?
F22. I'm a smoker and tend to drink alcohol at least weekly. For the past week, I’ve noticed painful lesions on the upper part of my mouth and my gums. They appear white with reddish edges. I have an appointment with my dentist and am currently using mouth rinses, along with herpes medication and topical ointments. Additionally, I have some sores on my lips, leading to the conclusion that I might be experiencing a herpes outbreak. However, I’ve never previously experienced herpes symptoms. I conducted blood tests that revealed my immune system is quite weak; all signs suggest it could indeed be herpes, but I've never encountered such symptoms before and am uncertain about their nature. I'm concerned this might indicate a more serious health issue.
Is It Too Late for Conservative Treatment?
I'm a 30-year-old woman working in marketing, spending the majority of my time in front of a computer, and I primarily use my right hand. I deal with several health issues including Crohn’s disease, hypothyroidism, and POTS. My current medications are Skyrizi, Synthroid, Metoprolol, and Slynd. Recently, I've been experiencing discomfort primarily in the last month, although it has lingered for a few months now. I live in the United States. I consulted an upper extremity surgeon due to persistent numbness affecting my right fourth and fifth fingers, as well as my palm and the back of my hand. Having previously undergone surgery for cubital tunnel syndrome on my left side after a nerve injury, I was somewhat familiar with what I was dealing with. That surgical procedure involved a submuscular transposition, which I have no regrets about. Before seeking medical advice, I utilized tips I learned previously and invested in an ergonomic mouse and an elbow pad. During my last visit, my doctor provided me with a night splint and advised that I use a brace during the day for additional support. However, the nighttime splinting hasn't been effective; I consistently wake up to find it removed, with no memory of doing so. After a brief examination, the surgeon recommended an EMG. He indicated it was likely cubital tunnel syndrome but wanted further confirmation of its severity. During his assessment, he noted a slight weakness in my hand, which I concurred with, recalling a recent incident where I dropped a salt shaker multiple times just a week before our meeting. I had the EMG done recently, and the results showed that both the median and radial nerves were functioning well, but there were no sensory signals detected from my ulnar nerve at the cubital tunnel. Fortunately, the nerve appeared normal both above and below the elbow, and there was no indication that my muscles had been compromised during the tests. The EMG specialist remarked, "there's a complete block at your elbow," after multiple nerve conduction studies in that area. He also observed that my elbows hyperextend, which he suggested could be contributing to my issues, though he didn't believe there was any weakness in my hands. I pressed for further explanation regarding my condition and he clarified that without addressing the compression, my situation would likely deteriorate, but he also noted that he wasn’t a surgeon. This raises a question: Is it possible for me to recover fully and experience no symptoms in the future, or have I missed the opportunity for successful conservative treatment? I want to avoid rushing into surgery, yet I am not keen on prolonging my current struggles only to end up in the same place a few months down the road. I am seeking guidance on how to approach my upcoming appointment and what key points to consider.
Seeking Advice: Unusual Nasal Congestion
I am a 42-year-old woman seeking advice for a peculiar issue I’ve encountered. After utilizing a nasal spray for over two decades (not Afrin specifically, but a similar product), I am now undergoing withdrawal. Following a gradual tapering phase, I am now entering the fourth week without any spray. Currently, I rely on saline and ectoin sprays due to the extreme sensitivity of my nasal passages, which seem to worsen with the use of steroids and antihistamines. My concern revolves around a peculiar congestion that is primarily localized at the base of my nostrils, with no discomfort felt in my sinuses or deeper inside my nose. My ENT remarked that my nasal health appears to be improving and was quite surprised when I mentioned this specific congestion issue. I proposed that heightened sensitivity in the nerves at the base of my nostrils might be a factor, to which she acknowledged the possibility but lacked certainty. Interestingly, my nasal condition seems to improve somewhat during the night and morning hours, with the most significant congestion manifesting in the afternoons. There is an absence of mucus, just a collection of damp boogers. Has anyone else experienced such a distinct type of congestion? I struggle to find information that matches my symptoms. I am aware that I have rhinitis medicamentosa, but I wish to comprehend whether it’s common to experience this sensation solely at the lower part of the nostrils.
