Persistent Lump on Arm for Over Two Decades
Greetings, I’m seeking guidance regarding a lump on my arm that has been present for more than twenty years. The size is comparable to a dime, and it has a noticeable bulge rather than being flat. The overall texture is quite solid, though there is a white section within that feels extremely hard, similar to a tooth. At times, it forms a scab, which occasionally falls off. However, it does not cause me any pain or discomfort. This lump is situated on the outer part of my left bicep. Thank you for any insights you can provide.

It's understandable to be concerned about a long-standing lump on your arm. Given that this lump has been present for over twenty years, it’s important to assess its characteristics carefully.
Key Points:
- The lump's longevity and characteristics (size, texture, and occasional scabbing) are notable.
- While it currently does not cause pain or discomfort, changes in appearance or symptoms can be concerning.
Explanation:
Lumps like the one you describe can be caused by a variety of conditions, including:
- Lipomas: Soft tissue tumors that are generally harmless and can feel rubbery.
- Dermatofibromas: Benign growths that are firm and can feel hard; they are usually skin-colored or brown.
- Cysts: These can develop in various tissues and may become scabbed if there’s irritation.
The hardness you mentioned, especially that feels like tooth enamel, may suggest a more specific type of growth. Since it has been around for a long time without significant changes or discomfort, it’s likely benign. However, any lump that is abnormal should ideally be evaluated to rule out anything more serious.
Next Steps:
- Monitor the Lump: Keep an eye on the lump for any changes in size, shape, color, or if it starts to cause discomfort.
- Maintain Good Hygiene: Avoid excessive irritation to the area to prevent scabbing or inflammation.
- Consider Documentation: Take a photo of the lump now and note any changes weekly. This can help if you decide to seek further evaluation.
- Seek Professional Evaluation: Although it doesn’t seem to be causing any issues now, if you have further concerns or if the lump changes, it may be wise to consult with a healthcare professional for a thorough examination and possibly imaging or biopsy if indicated.
Your concerns are valid, and taking these steps will help ensure that you remain aware of any potential changes. If you have more questions or need additional assistance, feel free to reach out!

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
