Concern About Armpit Lump
Hello everyone, I’m a 25-year-old female, standing 5 feet tall and weighing 180 pounds. I have been diagnosed with Hashimoto's disease and asthma. Recently, I've noticed a lump in my armpit. While it doesn’t cause me much discomfort on its own, it does feel sore if I accidentally bump it. I can't help but wonder about the potential causes, especially since it seems to be slightly increasing in size. In the past, I experienced a swollen lymph node on the same side, behind my ear, which eventually resolved itself. Any insights or thoughts on what this could be would be greatly appreciated!

It's understandable to feel concerned about a lump in your armpit, especially with your medical history. A lump in this area can have several explanations, ranging from normal anatomical variations to lymph nodes reacting to infection or inflammation. Since you have a history of swelling in nearby lymph nodes, this could potentially be related.
Explanation
Lumps in the armpit are often swollen lymph nodes responding to infections, injuries, or other issues. Given your Hashimoto's disease, your immune system may behave differently, which can sometimes lead to lymph node reactions. Factors like slight increases in size and soreness when bumped are noteworthy, but many times, these lumps are benign.
Next Steps
-
Monitor the Lump: Keep an eye on the size and any changes over the next 1-2 weeks. Note if it continues to grow, becomes more painful, or if you develop any other symptoms like fever or significant fatigue.
-
Symptom Diary: Record any additional symptoms you might experience, as well as details like when you first noticed the lump, any recent infections, or injuries.
-
Self-Care: Avoid any activities that might irritate the lump. If the area becomes very painful or bothersome, applying a warm compress may help ease discomfort.
-
Consultation Consideration: If the lump continues to grow, becomes more painful, or if you notice systemic symptoms (e.g., fever, weight loss, excessive fatigue), reaching out to a healthcare provider for further evaluation would be prudent.
It's important to remember that many lumps are harmless, but staying vigilant is key. If you have any further questions or requests for clarity, feel free to ask!

Recurring Strep Throat After Antibiotic Treatment
I’m a 26-year-old female, 5’2”, generally in decent health, taking daily medications including Wellbutrin, Zyrtec, and birth control. I was diagnosed with strep throat on July 30 after a swift test at an urgent care facility. My symptoms included painful swallowing, severely inflamed tonsils, nausea, and a lack of cough or fever. The treatment prescribed was amoxicillin, two pills daily for a duration of ten days. I completed this course, but within about 48 hours, I began to experience a resurgence of symptoms, including significant fatigue and widespread body aches. Consequently, I returned to urgent care, where I received a new prescription: cephalexin, taken three times daily for another ten days. I noticed an improvement and felt relatively normal for a few days, but unfortunately, the symptoms reappeared shortly after finishing that course of antibiotics. Just this past Friday, I completed my cephalexin regimen, and once again, I’m suffering from painful swallowing and inflamed tonsils. Throughout this ordeal lasting 20 days, I’ve made an effort to maintain my intake of probiotics and vitamins. Living alone without any pets, and being single, I’m fairly certain I’m not in contact with anyone who could be carrying the bacteria. At this point, I feel somewhat lost. Should I revisit urgent care to explore my options further and possibly request a culture to check for antibiotic resistance? Alternatively, would it be sensible to consult with an ear, nose, and throat specialist? Having recently relocated to a new state, I have not yet established a primary care physician. Any guidance would be greatly appreciated.
Advice Needed on Vaccinations for Unvaccinated Adult

Experiencing Temporary Blindness in One Eye: Seeking Guidance
At 35 years old, I am a male weighing 385 pounds and standing 6 feet tall. I deal with high blood pressure, have pre-diabetes, and regularly use a nicotine vape. Additionally, I am in recovery from alcoholism. As I lack health insurance and do not have a primary care physician (PCP), I’m uncertain about the best steps to take in order to manage my situation without incurring high costs. Here’s what transpired: Approximately a week ago, I awoke to find that I had completely lost vision in my left eye. There was no discomfort, tingling, confusion, or slurred speech—just sudden darkness. Fortunately, my sight gradually returned over about a minute. I promptly consulted an optometrist who dilated my affected eye. His examination revealed no abnormalities, leading him to suspect that the issue might originate from inadequate blood flow to the occipital lobe. He referred me to a PCP, submitting my information, but I have yet to receive any communication from them. Yesterday morning, the same incident occurred once again without warning. There is an ophthalmologist located roughly an hour away; would that be a good starting point for me? Given that an emergency room visit could potentially cost me a significant amount, I'm hesitant to wait on becoming a new patient for a PCP only to be referred again and face additional delays. Thank you for your assistance and advice.
Experiencing Temporary Blindness in One Eye: Seeking Advice
At 35 years old, I stand at 6 feet tall and weigh 385 pounds. My health history includes high blood pressure, pre-diabetes, and a reliance on nicotine through vaping, alongside being in recovery from alcohol use. Given my lack of health insurance and absence of a primary care physician (PCP), I’m looking for advice on managing costs while seeking medical attention. Recently, I experienced an alarming episode where I woke up and found I couldn’t see out of my left eye. There was no accompanying discomfort, slurring of speech, or any other disorienting symptoms. Fortunately, my vision gradually returned within approximately a minute. I consulted an optometrist who examined my eye and conducted dilation tests, revealing nothing unusual. He speculated that the issue might originate from blood flow to the occipital lobe. He recommended I connect with a PCP and submitted my details for a referral, but I have not yet received any communication. This unsettling incident recurred yesterday morning, with identical results. There is an ophthalmologist located about an hour from my home; should I consider making an appointment there? I’m apprehensive about an emergency room visit due to potential exorbitant expenses, and the idea of waiting months as a new patient to obtain a referral seems impractical. I appreciate any guidance you can provide.
Prominent Veins Noticed in My Feet
Subject: M28 / Height: 6'4" (199cm) / Weight: 145lbs (66kg) Existing Medical Conditions: - Possible Ehlers-Danlos (Joint Hypermobility) Hello everyone, Recently, I've observed that the veins on my left foot, in particular, have become very noticeable. This change has raised some concerns for me, especially considering I had both lower leg bones fractured in an accident around ten years ago. I'm beginning to wonder if that injury has led to some vascular issues, which might explain why the veins are more pronounced on that side. The appearance of these veins is causing me significant concern and anxiety. I can't help but fear that any injury in this area could lead to severe bleeding. Additionally, I'm starting to question if this could be an early indication of varicose veins. I would greatly appreciate any insights or thoughts on this matter.
