Unexpected Bump on My Finger

9/4/2025, 12:20:28 AMMale25-34

Age: 30, Height: 5'3", Weight: 116 lbs (ranges from 110 to 125 lbs) - Ethnicity: White/Hispanic Recently, I discovered a small bump on my finger right after I was cleaning some adhesive residue from my car's windshield. I’m quite certain this lump wasn’t present before I began the cleaning process, as I used that hand to scrub with a cloth and would have definitely noticed a small, red bump. Initially, the lump was tiny and red; however, it has grown to the size it currently is and has remained unchanged for several days. Additionally, I experienced a very painful protrusion on my elbow that lasted about 45 minutes before fading away. I often deal with eczema on my elbows and palms, and my first thought was that it might be an eczema flare-up. However, since I've never had hives, I'm uncertain about that. The only similar experience I've had was with a plantar wart on my foot, but this doesn’t seem like a wart given how swiftly it appeared. It isn’t a blister—there's no fluid involved, and it feels hard and tender. I now have a gut feeling that this could be a joint nodule stemming from some form of autoimmune arthritis. I've been undergoing treatment with a chiropractor and physical therapist for issues related to sciatica as well as tingling and numbness in my toes and fingers. Initially, I thought it might be a result of muscle tension or carpal tunnel syndrome. However, I've noticed that the discomfort worsens after consuming highly inflammatory foods, such as fast food or ice cream. I’ve been focusing on a diet rich in whole, clean foods for the past couple of months, which has improved my overall joint pain, yet this lump appeared unexpectedly. I hesitate to rush to my doctor about this issue since I've already been adopting their advice for managing arthritis—focusing on anti-inflammatory eating and engaging in low-impact exercises. I've dealt with joint aches and popping knees since I was a teenager, which adds to my concern. I take glucosamine/MSM and hyaluronic acid every day, and those have contributed to joint comfort over the last three years when the discomfort and joint noises increased. There was a time when I would wake up often due to knee pain that disturbed my sleep, but that situation has improved since I began chiropractic treatments. I would appreciate any insights or experiences related to this. Am I being overly concerned about this situation?

It's understandable to feel concerned about a new and painful bump on your finger, especially given your existing joint issues and experience with eczema. Here’s a breakdown of what you’re experiencing and steps you can take.

Main Points:

  • The bump and pain could be related to several conditions, including irritation from cleaning, an inflammatory response like eczema, or a possible cyst or nodule.
  • Pay careful attention to any changes in the bump’s appearance or symptoms you experience.

Explanation:

The lump on your finger may have appeared due to an irritation or a localized inflammatory reaction from cleaning the adhesive. Since you mentioned your history of eczema, it’s possible the bump could relate to that or perhaps even a minor allergic reaction. Additionally, bumps on fingers can sometimes be caused by ganglion cysts or other benign growths, particularly if they feel hard and tender.

Considering your mention of joint issues and diet, it’s good that you've shifted towards an anti-inflammatory diet, as this can help overall joint health. However, if this bump feels 'hard and tender' and persists, it's important to monitor it closely.

Next Steps:

  1. Monitor the Bump: Keep an eye on its size, color, and any associated symptoms (like pain or immobilization). If it changes significantly or worsens, this will be crucial information.

  2. Nurture Your Skin: Since you have a history of eczema, apply a gentle, fragrance-free moisturizer to the area to soothe it and prevent further irritation.

  3. Avoid Irritants: Be mindful of any products you use on your skin, especially around the time you found the bump. If you suspect it was related to the cleaning process, consider using protective gloves next time.

  4. Diet Awareness: Since you noted that inflammation worsens after eating certain foods, continue monitoring your diet for known triggers and maintain your current anti-inflammatory approach.

  5. Pain Management: If the bump is painful, consider using a cold compress on the area for short periods to reduce discomfort.

  6. Symptom Journal: Keep a record of any new symptoms, changes in the bump, and the context in which they occur (like after exercise or eating certain foods) to help identify patterns.

If any new concerning symptoms arise, such as severe pain, spreading redness, or changes in function (like difficulty using your hand), revisiting your healthcare provider would be advisable. Given your existing conditions and experiences, staying connected with your doctor for ongoing support is important, even if you don’t feel an immediate need to see them.

Seeking Advice on Bulging Veins Related to AS and Treatment

Greetings everyone, I’m reaching out for some guidance regarding recurrent bulging veins that are quite noticeable on my legs. At 33, I’ve been diagnosed with Ankylosing Spondylitis (AS). My condition includes significant nerve involvement due to my autoimmune disease alongside a few discs that are pressing against the thecal sac. I engage in some light exercises, primarily focusing on stretching and walking for cardio, but it’s not extensive. Currently, my medication regimen consists of 50mg of etanercept administered weekly, along with methotrexate dosages that vary between 5mg and 7.5mg each week. Additionally, I have been on prednisone for a few months now. Fortunately, my blood pressure readings are within normal limits, and both my liver and kidneys appear to be functioning well. I am also undergoing testosterone replacement therapy (TRT) and utilizing HCG to help maintain my fertility. I suspect that this recent development—occurring over the past couple of months—may be linked to the TRT, as these bulging veins tend to fluctuate significantly. They seem to worsen when I adjust my testosterone or HCG doses. Given these circumstances, I’m curious if reducing or pausing my TRT, along with beginning PCT and HCG, might alleviate these vein issues while also addressing my low testosterone levels. I will post pictures in the comments to illustrate the severity of the situation. Any advice or insights would be greatly appreciated. Thanks in advance for your responses!

Concerns Over Unpleasant Odor After Bathroom Use

Hello, Medical Professionals, I’m reaching out to discuss a delicate matter that’s been troubling us. Occasionally, after my mother uses the bathroom, an unpleasant odor permeates the area, and it’s quite distressing. We have concerns that she might not be receiving the proper medical attention she requires. The stench is incredibly intense, resembling that of a deceased animal left exposed to the elements for an extended period—akin to the scent of decomposing meat or perhaps even a rodent carcass hidden within the walls. Interestingly, this smell can persist for hours. Despite our efforts—turning on the exhaust fan, clearing the trash, flushing multiple times, and running the sink—the odor remains stubbornly present. At times, it even invades the entire house, and we can only eliminate it by thoroughly cleaning the bathroom with bleach. What could be causing this? My mother is approximately 78 years old, weighs around 170 pounds, and is 5 feet 6 inches tall. She is pre-diabetic and, in my opinion, consumes excessive amounts of sugar. Notably, she has a history of being a heavy smoker but quit some time ago. Additionally, we believe she may be struggling with depression, as her living space has become quite chaotic, though we’re uncertain about the extent of her emotional state. We would appreciate your guidance on what questions we should pose to her healthcare providers. Thank you for your assistance!

Florida Mom Seeking Guidance on Vaccine Concerns

Hello! I’m a parent of two children, aged 19 months and 4 months, residing in Florida. Ever since the confirmation of RFK, I’ve been on high alert, and it seems like my worries are becoming a reality. I’ve devised a few plans, but I’m curious if I might be overreacting or if my concerns are justified. - **MMRV Titer Tests for Close Family**: I’m considering having my husband and in-laws tested for MMRV titers since they frequently interact with my kids. This thought stems from my own experience during pregnancy when my blood tests indicated I lost immunity to varicella, leading to a booster shot post-delivery. It raises a question in my mind: could they be lacking in immunity as well? I would prefer them to be re-vaccinated if necessary. I believe my concerns are reasonable, especially given the situation with the COVID vaccine. Currently, my husband and I cannot receive a COVID shot at Walgreens due to changes in CDC recommendations. Additionally, with the MMR vaccine scheduled for discussion in the next meetings and RFK's contentious comments regarding its link to autism during a Senate hearing, I worry about future availability of this vital vaccine. In summary: Should regular caregivers of my children undergo titer testing and receive re-vaccination if needed? - **Updating the Polio Vaccine**: Although it may sound extreme given the lack of cases over the decades, I’m contemplating receiving a new polio vaccine. The titer test is quite pricey, and I’d rather just get the updated vaccine and be done with it. If the virus were to re-emerge and I transmitted it to my kids, I could never forgive myself. I’ve come across information suggesting this vaccine wouldn’t harm me— is this correct? Am I being overly cautious? I appreciate your time and insights. My admiration for healthcare professionals has always been high, but now, more than ever, I deeply value your unwavering commitment to providing compassionate, evidence-based care. The future often seems daunting, but you all are true heroes to me and my family.

Unexpected Rash on My Chin

I’m a 29-year-old female, weighed 108 pounds, and stand 5'5" tall. I experience eczema specifically affecting my lips, but at the moment, I’m not on any medication. This morning, I noticed a peculiar rash on my chin that resembles a hickey. I’m puzzled about its origin since my lips are relatively stable with no current flare-ups. The rash itself isn’t painful or itchy at all. Could this be an extension of my eczema? I appreciate any insights you can provide!

Feeling Uncertain About My Symptoms

I’m a 28-year-old male, standing at 6 feet 1 inch tall and weighing 190 pounds, and I struggle with significant panic disorder. For the past month, I’ve been experiencing a persistent headache concentrated in my right temple. Initially, this discomfort would only surface when I coughed, but it escalated to include sneezing and physical exertion. Recently, I awoke with this pain while at rest, and although it seems to radiate through my entire head, the primary sensation is localized in my temple area. Two days ago, I reached out to my physician to secure a referral for an MRI; this process is straightforward since I have previously been diagnosed with a pituitary adenoma. However, I find myself questioning whether to wait for the MRI or if I should head to the emergency room instead. My anxiety levels are quite high right now. Any guidance would be greatly appreciated.
