Red Semicircles on Nails: A Concern?
About two weeks ago, I observed something unusual: each of my nails developed a distinct red crescent shape toward the top. There's no pain associated with these marks, and when I apply pressure, they momentarily turn white. While some nails have faded significantly, others still display the red arches prominently. This past July has been particularly stressful for me. In response to my heightened anxiety, I consulted with my doctor. Initially, I was prescribed the following medications: - 125mg of lysine clonixinate - 5mg of cyclobenzaprine HCI This treatment aimed to reduce muscle tension that I had been experiencing continuously. After completing that course, my anxiety levels still felt excessively high, prompting another visit to my physician. This time, the recommendation included: - 6.5mg of amitriptyline - 2.5mg of chlordiazepoxide These medications have significantly alleviated my anxiety and stress. Despite this improvement, I remain perplexed by the persistent red arcs on my nails. So far, I haven't experienced any other accompanying symptoms, leaving me uncertain whether this is a side effect of the medications I've taken in the past month or simply an unrelated issue.

It’s understandable to feel concerned about the red semicircles on your nails, especially since they’re a new development. While these markings can sometimes indicate underlying health issues, in many cases, they can be benign. Let’s explore what you’re experiencing and discuss some practical steps to take.
Explanation
The red crescent shapes you see on your nails, also known as "lunulae," can stem from several factors, including changes in blood flow, nail growth patterns, or even stress. Stress and anxiety can impact your body's systems, potentially reflecting physically on your nails. The fact that you’re not experiencing any pain and that the marks have faded on some nails suggests they may not be a serious concern at this point.
While medications like amitriptyline and chlordiazepoxide can sometimes lead to changes in nail appearance, these changes aren't commonly documented as side effects. However, individual reactions can vary.
Next Steps
-
Observe Changes: Continue to monitor the appearance of your nails over the next few weeks. Pay attention to any changes in color, shape, or if any additional symptoms arise.
-
Improve Nail Care: Keep your nails clean and moisturized. Regularly applying a hydrating lotion can help maintain nail health and may lessen unusual markings.
-
Manage Stress: Since you've mentioned stress as a factor, consider implementing relaxation techniques like mindfulness, meditation, or gentle exercise. These can further benefit both your mental health and possibly your physical symptoms.
-
Diet and Hydration: Focus on a balanced diet rich in vitamins and minerals (especially biotin and zinc) to promote healthy nail growth. Additionally, ensure you are well-hydrated.
-
Document Symptoms: Keep a simple diary of your nail changes and any stress levels or medication usage. This can help if you decide to discuss these changes with a healthcare professional later.
If you notice worsening symptoms, such as pain, discoloration beyond what you've described, or significant changes in your overall health, it might be worth revisiting your doctor for further evaluation. In the meantime, practicing self-care and being mindful of your body’s signals can be very beneficial. Let me know if you have further questions or if you need assistance!

Duration of Sensitivity After Circumcision
At 23 years old and hailing from Denmark, I recently underwent circumcision just two weeks ago. This procedure became necessary due to the snug fit of my foreskin, which had always kept the head of my penis concealed. Currently, the bleeding has ceased, and I’m able to move freely without the need for a bandage. However, I am experiencing significant sensitivity in the head of my penis, making walking quite uncomfortable. I’m curious if anyone has insights on how long this sensitivity typically lasts before it becomes manageable?
Concerns Regarding a Red Area on the Penis Glans
Age: 34 Gender: Male Weight: 60 kg Ethnicity: Caucasian Height: 167 cm I previously shared my concerns about a red area on the glans of my penis, and it seems that the patch has increased in size since then. I have scheduled an appointment with a urologist for this Thursday, which was the soonest availability I could find. I am feeling anxious about the possibility of cancer. Additionally, the skin of my foreskin is exhibiting redness and is quite painful when I attempt to retract it. I should note that I am a long-time heavy smoker.
Understanding My Blood Test Results: Should I Be Concerned?
I recently received my blood test results and my neutrophil count stands at 37.8 while the lymphocyte count is at 46.7. Additionally, my total white blood cell count is recorded at 7.79. This is the first time I’ve seen these figures, and I must admit they have caused me quite a bit of anxiety. Over the past several months, I have been under significant stress, experienced a prolonged episode of depression, and was diagnosed with a severe anxiety disorder. It's worth noting that I haven't yet started any medication. At 21 years old and being on the underweight side, I can't help but wonder if I should be concerned about these test results.
Should I Seek Further Imaging After My Injury?
**Context:** I am a 34-year-old person (AFAB) without any chronic ailments or significant past injuries. Recently, I experienced a fall down some stairs, where I landed awkwardly, absorbing the impact with my elbows. Imagine slipping on a staircase coated in ice, sending your feet forward while your back meets the ground. The pain was immediate and, quite frankly, the most intense I’ve ever encountered. I felt dazed and had to call my spouse to come home from work to assist me. My left arm swelled significantly from the elbow down, and I found it impossible to bend it past a right angle; the most comfortable position was to keep it extended straight out. Despite several attempts to visit urgent care facilities, we were faced with closures or high patient volumes, a typical issue in a semi-rural area. Eventually, we went to the emergency room. They performed X-rays on my left forearm, capturing images while it was bent at 90 degrees and in various positions. The diagnosis was a major soft tissue injury, indicating no fractures were present. I was advised to apply the RICE method (Rest, Ice, Compression, Elevation), use a sling for 48 hours, manage the pain with ibuprofen and Tylenol, and return if symptoms persisted beyond a week. I must admit, the incident stirred up quite an emotional response. The pain was unlike anything I had previously experienced, and reflecting on my childhood experience when my broken leg went untreated for days by my parents heightened my sensitivity to pain being overlooked. My mother-in-law, a Nurse Practitioner, was in constant communication, helping clarify medical details, and even she found it concerning that it was the emergency doctor who assessed my X-rays instead of a radiologist. Regardless, the X-ray results indicated no fractures, which was ultimately a relief, leading us to leave the hospital. **Now fast forward:** I upheld RICE for 72 hours, leading to reduced swelling. The bruising remains, though it has transitioned to a softer yellow hue, surfacing as the injury’s depth lessens. After a week and a half, I regained nearly full function of my arm with minimal swelling. However, there’s a troubling aspect. Whenever I apply pressure to either elbow, such as when I try to prop myself up in bed, I experience a quick, sharp pain followed by throbbing discomfort. Although the left arm, the one that suffered the injury, is notably worse, there’s also a milder pain in my right elbow. My mother-in-law is concerned that there might be a hairline fracture at the elbow's base that could have been overlooked. She suggests that I return for further imaging or at least get a consultation with my primary care provider, who is a Family Nurse Practitioner. However, I’m currently not in a position to bear the financial burden of a second ER visit and question if it’s truly necessary, especially since I can continue to rest my arm and avoid leaning on it for a while longer. **In summary:** Could the ER have possibly missed hairline fractures, and should I seek another evaluation?
Should I Request a Correction to My Surgery Record?
Age: 49 Gender: Female Height: 5'9" (69 inches) Weight: 270 lbs Ethnicity: White Summary: I’m contemplating whether to ask for a correction to my surgical record as it contains conflicting information from what my surgeon communicated to me. About nine weeks ago, I underwent a vertical sleeve gastrectomy. Overall, the recovery process has been extremely positive. However, I encountered a significant rash on my abdomen during the first six weeks of recovery. My previous experience with a hysterectomy in 2018 informed me that my skin is sensitive to surgical glue, and I conveyed this to my bariatric surgeon during the initial consultation. He assured me, saying, "No problem, just remind me, since I usually use glue." I made it a point to remind him on multiple occasions, including on the morning of the procedure, and he reaffirmed that we would use steri-strips instead. Post-surgery, I noticed that there was no trace of glue but only steri-strips on my skin. As the rash worsened, I was instructed to remove the steri-strips. During my two-week follow-up appointment, the surgeon, who was genuinely pleasant, indicated that given my reaction to the steri-strips, I might struggle to manage any type of wound dressing. He chuckled and advised, “try to avoid future surgeries.” Despite following his advice, the hives, peeling, and blisters continued. After six weeks and three appointments with my dermatologist, a biopsy was performed, which suggested a likelihood of a drug interaction. It turned out that I was reacting to Pantoprazole, a medication I began taking the day after the surgery. Once I discontinued it, my condition improved significantly. However, I later reviewed my surgical documentation in MyChart, where the operation note states, "Skin was closed using 4-0 Monocryl subcuticular sutures and surgical skin glue.” During a follow-up appointment, I expressed my concern about this discrepancy to a Nurse Practitioner in the Bariatric department. She recommended that I reach out to the PA who assists in surgeries for the surgeon to amend the record. She seemed reluctant to address the matter directly with the surgeon herself. Given this situation, do I reach out to the PA about correcting the record, or should I just let this matter slide like Elsa from Frozen?
