[44M] Awoke with Severe Itchiness Underarms
I’m a 44-year-old male, weighing 162 pounds and standing 5'11". I currently take medication for cholesterol but am otherwise in good health, with recent blood tests from June showing all parameters within normal ranges, including A1C and cholesterol levels. Last night, I noticed some reddened patches under my arms, which have become quite itchy. I tend to sweat profusely, especially during this recent heat wave. A few years back, I encountered a similar issue where I applied diaper rash ointment for two weeks, but this is noticeably larger and located deeper within the armpit area compared to that previous instance, which was merely a small irritation. Given the itchiness, I likely scratched the area while sleeping. I’ve recently stopped using my deodorant, Schmidt’s Natural, due to the irritation, so I doubt that’s the cause, especially since that brand is known for being gentle on the skin. Could anyone shed some light on what this might be?

Itchiness and redness under the arms can be quite uncomfortable, and there are several potential causes. Considering your description, this could be due to a condition known as intertrigo, which often occurs in warm, moist areas of the body like the armpits, particularly with increased sweating. Other possibilities include allergic reactions, fungal infections, or dermatitis.
Explanation:
- Intertrigo: This condition arises when skin rubs against skin, leading to irritation, especially in sweaty areas. The presence of redness and itchiness fits this description.
- Fungal Infections: A yeast infection (such as Candida) can occur in skin folds, leading to rash and itchiness as well.
- Contact Dermatitis: Even though you stopped using your deodorant due to irritation, it’s still possible that another product or even sweat can cause a skin reaction.
Next Steps:
-
Keep the Area Dry: After showering, ensure your underarms are dry and consider using a cooling powder to absorb moisture. This will help prevent further irritation.
-
Avoid Scratching: To minimize further irritation and potential infection due to scratching, try to leave the area alone as much as possible.
-
Use Over-the-Counter Treatments: Applying a mild hydrocortisone cream can help reduce itchiness and inflammation. If you suspect a fungal infection, an antifungal cream may also be beneficial.
-
Monitor Symptoms: Keep an eye on the rash for a few days. If it starts to spread, becomes more painful, or fails to improve with the above measures, it may require more specialized treatment.
-
Consider Your Environment: As the weather is hot, try to wear breathable fabrics and avoid tight clothing that may exacerbate friction in the area.
These steps should help alleviate your symptoms, but please feel free to reach out if you have further questions or if your symptoms do not improve.

Experiencing a Pinched Nerve Near the Shoulder Blade
At 25 years old, and without any previous health issues or medications, I suddenly find myself dealing with a pinched nerve in my shoulder. The cause is unclear to me. I've encountered pinched nerves before, primarily in my neck, but this experience feels distinctly different. It's only been three days, yet the pain has rendered me nearly incapacitated. Simple tasks like using the bathroom, sleeping, and even showering have become incredibly challenging due to significant pain and restricted movement. After looking into this condition, I’ve learned that recovery may take anywhere from four to six weeks, a timeline I'm not equipped to manage given the intensity of my discomfort. My profession involves physical activity, and my hobbies mirror that requirement. In an effort to find relief, I have tried a variety of approaches: alternating ice and heat, taking over-the-counter pain relievers like Tylenol and Advil, resting whenever possible, and incorporating stretches recommended in online videos. Unfortunately, nothing seems to alleviate the pain. I’m reaching out for guidance. Would physical therapy be beneficial in my situation? Are there particular stretches known to provide relief for pinched nerves? A friend of mine mentioned that muscle relaxants failed to help her during a similar episode; should I consider trying them nonetheless? Is visiting a doctor necessary at this point? I appreciate any advice you can provide to help me navigate this painful situation.
Is Constipation Possible Without Symptoms?
For me, experiencing a lack of bowel movements for a span of 8 to 10 days on a monthly basis is quite common, and I suspect it is linked to my premenstrual syndrome, as it consistently occurs during the same week every month. However, I find myself questioning whether this situation qualifies as constipation, mainly because I do not exhibit any classic signs. There is no pain, no discomfort, and no bloating; I genuinely feel as though there is no urgent need to relieve myself. I am 24 years old.

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.

Has anyone opted for antibiotics rather than surgical intervention? What was your experience like?
