Unexpected Armpit Irritation This Morning Despite No Changes
Hello everyone, I genuinely appreciate you taking a moment to read this. This morning started off like any other for me. After completing my usual morning routine—brushing my teeth and taking my daily dose of Duoloxetine (20 mg twice daily)—I applied my deodorant, slipped on my T-shirt, and headed downstairs for breakfast. While I was finishing my meal, I began to feel some discomfort in my armpits. As I moved around, the irritation intensified significantly. Upon glancing in the mirror, I noticed the early signs of a light rash forming in the folds of my armpits. To remedy the situation, I decided to take a shower and opted for more comfortable, loose-fitting attire afterwards. At this point, my armpits are still quite irritated, though I’m not overly concerned. At worst, it seems I might need to switch my deodorant, clothing, or detergent brand. What puzzles me, however, is the fact that this irritation occurred simultaneously on both sides without any new factors influencing this sudden change. I've been wearing the same brand and type of t-shirt almost daily for three years now, and the deodorant stick I used has been a regular for about a week, while I’ve been using the same type of deodorant for five years. Similarly, I’ve stuck with Arm & Hammer laundry detergent for the last eight years. If only one side were affected, I might shrug it off, but the fact that both armpits are irritated at the same time has me curious about the underlying biological reasons. I would greatly value any insights you might have. Thank you immensely!

Thank you for sharing your experience. It's understandable to be concerned about the unexpected irritation in your armpits, especially since it’s occurring symmetrically on both sides. Here’s a breakdown of what might be happening and some steps you can take.
Main Points:
- The sudden armpit irritation could be due to a variety of factors including allergic reactions, irritation from your deodorant, or changes in skin conditions.
- Monitoring symptoms and making a few adjustments could help alleviate the discomfort.
Explanation: The irritation you’re experiencing can stem from several possible causes, such as:
- Contact Dermatitis: This can occur from direct irritation or an allergic reaction to your deodorant, detergent, or even materials in your clothing.
- Heat and Moisture: Sometimes, excessive sweating or humidity can cause skin irritation in areas like the armpits, especially if wearing snug clothing.
- Skin Condition: Conditions like eczema or fungal infections can flare up under certain circumstances, leading to rashes.
The fact that both armpits are affected could suggest an allergic reaction or shared exposure to an irritant, rather than a localized skin issue.
Next Steps:
- Stop Using the Deodorant: Avoid using the deodorant that you applied today to see if the irritation subsides over the next few days.
- Keep the Area Clean and Dry: After showering, gently pat the area dry and consider using a mild, fragrance-free soap.
- Wear Loose Clothing: Continue to wear loose-fitting clothes to minimize friction and irritation.
- Apply a Soothing Ointment: If you have any over-the-counter hydrocortisone cream or aloe vera gel, applying a thin layer may help reduce inflammation and discomfort.
- Monitor for Allergic Reactions: Track your symptoms over a few days. If the rash worsens, leads to severe discomfort, or if you see signs of infection (increased redness, swelling, or pus), seek further assistance.
If symptoms persist or worsen after these steps, consider reevaluating your products or consulting a healthcare provider. Please feel free to reach out if you have more questions or need further assistance!

Chronic Foot Pain: Seeking Insights on Possible Causes
I'm reaching out to gather thoughts on a perplexing issue I'm facing. Since my first pregnancy back in 2020, I've been dealing with intense foot pain that appears unpredictably. It all started when I was about seven months along while working long shifts in a busy kitchen, four days a week, for eight hours each day. At the time, I dismissed the discomfort as something typical for pregnancy, but it fortunately subsided about six months after giving birth to my first child. Fast forward to late 2024, when I became pregnant with my second child. By now, I had transitioned to being a stay-at-home mother, with none of the rigorous demands of my previous job. However, around three months into this new pregnancy, the foot pain reemerged and has persisted ever since. My youngest is turning two this month, which helps frame this timeline. The pain has oscillated between being severe and manageable, but the previous six months have marked a significant decline into debilitating territory. When I am at rest, I feel sharp pains in my metatarsals that radiate up to my knees. To alleviate some discomfort, I’ve been altering my walking style to shift weight more onto my heels instead of the balls of my feet. However, this adjustment has introduced a new level of discomfort in my heels. Ironically, the only relief I find is while walking. Nonetheless, excessive walking—even something as simple as taking my oldest to school for a brief ten-minute journey—leaves me nearly immobilized the following day. Currently, I’m on a regimen of 50 mg of APO-Diclofenac DR, taken twice daily, yet I’ve found no relief. Previously, I also tried 500 mg of naproxen twice a day without any positive outcomes. I've experimented with various footwear, but none have alleviated the pain. My primary care physician has arranged for bilateral x-rays and blood tests to check for conditions like gout and markers for osteoarthritis and rheumatoid arthritis, among other things. So far, all tests have returned normal. There have been occasions where I’ve had to keep my oldest child at home from school simply because I’m unable to walk even a short distance, such as the fifty steps from my bedroom to the kitchen. Standing causes distress, and even elevating my feet while resting feels unbearable. Additionally, any gentle touch to my feet triggers intense pain that shoots up my shins. The only feedback I’ve received from my doctor so far is that it likely stems from inflammation, along with a recommendation to expedite weight loss. I had a chiropractor assess my condition, and they noted that I am hypermobile, but I’m unsure how significant that could be to my situation. If you have any questions for clarification, I’d be more than willing to respond. I’m enduring considerable pain and would greatly appreciate any suggestions on possible avenues for finding relief.
Managing Pain with Lidocaine Patches and Heating Pads
Hello everyone! I need to share something quite personal: I have been diagnosed with cancer. I realize that’s a heavy way to start, but it’s important context. Currently, I am using a lidocaine patch as a method for pain relief. However, I’ve found that my heating pad provides more comfort than the patch does. Is it advisable to remove the patch and switch to the heating pad instead? Should I clean my back prior to using the pad, even though it’s not a day I usually shower? Also, once I take off the patch, how long should I wait before applying the heating pad again? I appreciate any advice you have! For reference, I’m approximately 5 feet 5 inches tall and weigh around 250 pounds.
Discomfort Under My Big Toe – Seeking Diagnosis
I’m a 22-year-old male. About a week ago, I noticed a minor ache in my big toe, which didn’t bother me too much at the time, so I decided to brush it off. However, by yesterday, the discomfort had intensified significantly. I also observed some swelling and a bit of discoloration, but I'm unsure whether this issue stems from a corn, a blister, or something else entirely. I would greatly appreciate any assistance in identifying what might be going on.
Understanding Limited Finger Mobility and Associated Discomfort
I’ve noticed that my right hand struggles with having individual finger movement. To illustrate this challenge, I recently recorded a brief video showcasing my hand's limitations. Additionally, I’ve been dealing with persistent neck and shoulder pain for several years now. Despite consulting multiple healthcare professionals, I’ve yet to receive any conclusive answers regarding my condition. I’m currently attending physical therapy, but even my therapist seems puzzled by the situation. An MRI of my neck returned results indicating only mild issues, and the same goes for my shoulder, with nothing alarming detected. I would be immensely grateful for any insights or suggestions, particularly since the discomfort has forced me to halt my weightlifting training.
Experiencing Neck Pain for Almost a Week: Is It a Cause for Concern?
I want to be open about my situation, as I've shared my concerns in a few places without much input, so I’m hoping for more engagement here. Last Saturday, January 30, I finished a lengthy car journey and felt completely fine upon returning home. However, on January 31, I woke up to excruciating pain in my neck, particularly at the junction of my cervical and thoracic spine. The discomfort made any movement difficult, and tilting my head back was particularly painful, making it challenging to drink fluids or take medication. On a pain scale, it settled at a constant 6, with episodes rising to 8 or 9. Interestingly, I hadn’t sustained any injury that could explain this sudden pain, nor had I felt discomfort while resting. By the following day, I experienced a slight reduction in pain and regained some range of motion, but the sharpness remained. Any attempt to move my neck beyond its current limits was still extremely painful. I noticed that when I tilted my head side to side and then brought it back to center, I felt additional pressure midway, almost as if my vertebrae were struggling to move over a disc. Currently, I'm still feeling the effects of this issue. The area is stiff and sensitive. While the muscles surrounding it don’t ache, the joint itself is quite painful. Although I can move my neck now, it remains uncomfortable, leaving me uncertain about whether to wait it out or consult a doctor. I have a chiropractor appointment scheduled for this upcoming Tuesday, but I’m hesitant about whether I should allow them to adjust my neck. I plan to inform them about my condition, as I want them to make an informed decision regarding adjustments, but I’m unsure if I should proactively refuse any neck manipulation if it’s suggested. Additionally, I’m concerned about the possibility of a serious issue with my disc. Although I am trying to keep my worries in check, I can’t help but feel anxious about it. Another consideration is that my hips and lower back also feel misaligned, and I haven’t been able to correct that myself. If possible, I would still prefer to go to the chiropractor to address those areas. The only feedback I received from my previous post was advice against any adjustments, and when I inquired about my lower back and hips, I didn’t receive any clarification—just downvotes instead. Any insights or experiences you can share would be greatly appreciated!
