Rash in the Armpit Area
Profile: 27-year-old transgender male, Height: 5'7, Weight: 12 stone 12 pounds. Medical Background: 18 days following a double incision mastectomy, currently on IM Sustanon 250mg (for three weeks), daily methylphenidate hydrochloride, and Salofalk. Also takes paracetamol and tramadol as necessary. No smoking, alcohol, or drug use. I am currently 18 days post-operative from my top surgery, which initially restricted my movement due to pain for approximately 8 days. Thankfully, I've been gradually regaining my mobility. At present, I can move around quite comfortably, provided I don’t lift my arms excessively or twist my upper body. However, about two to three days ago, I noticed a sudden onset of a rash under both arms. The rash appears red and somewhat inflamed, with a distinct sharp edge, and it has become increasingly uncomfortable. Additionally, there is an unpleasant odor reminiscent of body odor, which is particularly frustrating as I have maintained my hygiene practices diligently. Despite washing daily, this smell returns shortly after, even though it dissipates temporarily. I have been using a gentle body wash (usually Sanex) along with the salt of the earth natural deodorant, both of which have worked well in the past, but they seem ineffective now. I’ll provide images in the comments for reference. What steps or products can I use to eliminate this smell promptly and address the rash? Ideally, I would prefer options available at a pharmacy, considering I live in a small town where the local doctor serves multiple areas, leading to long wait times for appointments.

It sounds like you're experiencing a troublesome rash along with an odor under your arms following your surgery. This can be concerning, especially given your recent double incision mastectomy. The rash and odor might be related to irritation, infection, or a reaction to products, especially as your skin heals. Let's address your needs and outline some practical steps to help relieve your symptoms.
Main Points:
- The rash could be a sign of irritation or an infection.
- Maintaining cleanliness while allowing the area to heal is important.
- There are OTC products that can help manage odor and soothe irritation.
Explanation:
After surgery, it's common for the skin to become sensitive, and factors like sweat and moisture can cause rashes in areas of friction, such as the armpits. The redness and discomfort you're experiencing might be due to irritation or perhaps a mild infection, especially considering the sharp edges of the rash. The odor could stem from bacteria growing in the warm, moist environment created under your arms.
Next Steps:
-
Keep the Area Clean and Dry:
- Gently wash your armpits with a mild, unscented soap to avoid further irritation. You might try using a gentle antiseptic wash, like hibiscus or tea tree oil soap, but be cautious if you haven't used these before.
-
Apply a Barrier Cream:
- After cleaning, consider applying a barrier cream (like zinc oxide ointment or a hypoallergenic moisturizer) to protect the skin from friction and moisture. This can help soothe the rash and reduce odor.
-
Use an Antimicrobial Deodorant:
- Look for a fragrance-free, alcohol-free deodorant containing antimicrobial properties (like baking soda or witch hazel) to help manage odor without irritating the skin further.
-
Avoid Excessive Moisture:
- Allow for airflow to the area as much as possible. If you're comfortable, try to wear loose-fitting clothing to minimize sweat accumulation.
-
Monitor Symptoms:
- Keep an eye on the rash for any signs of progression, such as worsening pain, increased redness, or discharge. If the condition worsens or doesn’t improve with these measures within a week, consider reaching out to a healthcare provider.
Additional Consideration:
Due to the potential for infection or more severe irritation, if you have access to an online consultation or can use telehealth services, it may be beneficial to get professional insight, especially if you're worried about infection.
Please know that healing takes time, and being proactive about your care can help alleviate symptoms. If you have any more questions or need further details on any of the steps, feel free to ask!

Assessing the Safety of Iron Infusions
As a 28-year-old female, I am facing the necessity of undergoing iron infusions due to a diagnosis of iron deficiency without anemia. This condition comes with constant feelings of extreme exhaustion and fatigue, with my ferritin levels at a meager 3. Balancing this struggle is particularly challenging as I am a mother to a young child, and the fatigue is significantly impacting my daily life. I have previously attempted to manage my iron levels with oral supplements, but this approach only leads to severe nausea and reflux symptoms. Additionally, I grapple with panic attacks, which raises several concerns regarding the infusion process: 1. My vitals might register unusually high due to my anxiety, and I fear that medical staff may misinterpret this as an allergic reaction to the treatment. 2. The possibility of experiencing anaphylaxis during the infusions terrifies me, especially after hearing various accounts of individuals who faced severe allergic reactions, either immediately or after multiple treatments. I acknowledge that these fears may stem from "what if" scenarios, yet they weigh heavily on my mind, and I find myself questioning whether my worries are excessive. In terms of my medical background, I live with irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD), alongside my specific iron deficiency issue. I also have a history of panic disorder, which adds complexity to my health picture, although my childbirth experience was uncomplicated. My gallbladder has been removed, and I have struggled with depression. On the family health front, there is a prevalence of high blood pressure, kidney disease, and anxiety. As for my physical stats, I stand approximately 5 feet tall and weigh around 170 pounds. Given this context, I am seeking reassurance and guidance regarding the safety of iron infusions for my situation.
Understanding a Red Bump Near the Uvula: What Could It Indicate?
Hello, I am seeking some advice. I'm a 23-year-old male, and I've experienced this condition in the past. It disappeared for about two weeks, but now it has returned. I have noticed a red area and a bump on the right side of my throat. It doesn't feel like a typical sore throat, but swallowing on the right side is somewhat painful where the bump is located. The redness appears more intense than it appears in photos, as the flash tends to wash it out, yet it extends towards the uvula. My doctor first identified it as pharyngitis, but after a follow-up visit due to the persistence of symptoms, I was told it might be a new variant of COVID-19. However, I am skeptical about both diagnoses. Thank you for your help!

Unveiling My TB Diagnosis: Was This the Cause of My Past Illness?
At age 23 and living in the USA, I recently embarked on a new job at a hospital which mandated a tuberculosis (TB) blood test. The results were unexpected – a positive diagnosis! Although I don’t have any current symptoms and have scheduled a chest x-ray for Monday, I can still commence work in a few weeks, albeit with additional requirements to fulfill in the meantime. Reflecting on my health issues from two years ago, I experienced a severe illness while at college. During that time, I was socializing frequently, attending fraternity parties, and consuming around 6-8 drinks weekly, which I'm sensitive to. What began as a simple cough rapidly escalated into something far more alarming. I've always dealt with recurrent coughs during colds, having experienced bronchitis multiple times and one incident of pneumonia, but this was on an entirely different level. The cough became so intense that it kept me awake at night, rendering me unable to retain food or water. I was vomiting anywhere from five to ten times daily due to the persistent coughing. In a span of three to four months, I lost 60 pounds. While I coughed up white lumps, I thankfully never saw blood. Ultimately, I had to resign from my job and struggled academically because I was often confined to my home. Even though it was winter in the Northeast, stepping outside felt overwhelmingly hot. Living alone without a partner or nearby family made matters worse, and I hesitated to disclose the severity of my situation to friends, leading to considerable isolation. Over this period, I visited the doctor more than seven times, and my condition escalated to the point where I needed hospitalization twice, often losing consciousness and experiencing hallucinations—on one occasion, I fainted in the hospital lobby. The medical team ran an exhaustive panel of tests, screening for a wide array of illnesses: COVID-19, various strains of influenza, RSV, a number of coronaviruses, parainfluenza viruses, adenovirus, and several others, including mycoplasma pneumoniae. After two clear chest x-rays ruled out pneumonia, I eventually received a positive result for rhinovirus. The doctors suspected a combination of a bacterial infection alongside the rhinovirus. Although I underwent multiple rounds of antibiotics during this time, none provided a sustainable solution. The hospital managed to give me intravenous steroids and antibiotics that offered temporary relief, but my condition soon worsened again. The height of this health crisis spanned from mid-October to mid-December. It wasn’t until I returned home for the holidays and allowed myself 12-15 hours of sleep daily that I began to recover. It took an additional six months to regain my lost weight, though thankfully, the cough eventually subsided. With this new diagnosis of latent tuberculosis, I'm left wondering if it could have been the reason behind my earlier ordeal, or was it solely a severe case of rhinovirus? I reviewed my medical history and noticed TB testing hadn’t been conducted. Is it possible for TB to shift from an active state to a latent one? Can a person's immune system conquer an active infection? For context, I've only traveled abroad once in the past seven years, which was to Europe within the last three months. Additional note: I still have my tonsils intact.
