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!

Understanding Kidney Pain: Should You Be Concerned?
As a 15-year-old assigned female at birth (AFAB), I've been dealing with acid reflux, although I've been neglecting to take any supplements. I also have scoliosis, which I doubt is linked to my current issue. Recently, I have been experiencing pain in my kidney area, specifically in my back, where my kidneys are situated. My mother suggested that this discomfort might indeed stem from my kidneys. For several months now, I haven't pinpointed the cause. I typically consume about 1 to 1.5 liters of water daily, and occasionally I drink cola, though I've reduced that due to my reflux. I sometimes have peach juice or plain tea, but those drinks have become quite infrequent. Despite my fluid intake, it seems my pain level remains consistent regardless of what I drink. The pain primarily affects my right kidney, but during more intense episodes, I also feel discomfort in my left kidney. I've tried lying down and applying gentle pressure to the area, which provides a bit of relief. Aside from occasional bladder discomfort today, I haven't experienced any additional pain that relates to my kidneys, aside from the persistent back pain from scoliosis and the usual stomach and chest pains from my reflux. Is it necessary for me to consult a doctor about this concern? 🥺 I am hesitant to go unless it's truly serious because I was hospitalized last summer due to undiagnosed tics and twitches—likely anxiety-related—and I spent the entire winter seeing doctors for this issue and my scoliosis. I’m also worried about missing school due to more medical appointments, especially since my doctor has a packed schedule, and I'm uncertain if she would prioritize my concern if it doesn't seem urgent. When I was hospitalized last summer, tests including urine and blood analysis showed no significant issues, so I'm unsure whether this warrants another visit now.
Persistent Shin Discomfort
For the past year, I have been grappling with ongoing discomfort in my shins. Despite consulting multiple physiotherapists and doctors, I have yet to find a solution to my problem. My routine has included extensive strength training targeting my hips, glutes, calves, and lower leg muscles. I've also taken steps to improve my running form and have experimented with various recovery techniques, such as foam rolling and using massage devices. No matter what I try, the pain persists, specifically on the inner side of my lower legs. Initially, I suspected that I was suffering from shin splints. However, given my varied attempts at treatment and the lack of improvement, I am starting to believe that the issue might be something different. Even mundane activities, like walking around at home, have become increasingly uncomfortable, not to mention my inability to ride a stationary bike without experiencing pain. If anyone has any insights or recommendations that could assist me in alleviating this issue, I would be extremely grateful. Thank you for your help!

Seeking Guidance on Ice Treatment Post-Surgery
I’m a 34-year-old male, weighing 158 pounds and standing 5 feet 6 inches tall. I lead a non-smoking lifestyle, consume three alcoholic drinks weekly, and do not have any known allergies. I'm currently recovering from right hand and wrist surgery, which took place five weeks ago. I need some advice regarding the use of ice for my treatment, as my wrist remains quite swollen. While I understand the advantages of icing, I find the experience quite intolerable. I attempt to immerse my hand and wrist in ice water completely, but the pain is so intense that I can barely last more than 15 seconds. Is this a challenge of mental resilience where I need to push through the discomfort for the sake of a proper 10-minute soak? In the past, I worked with racehorses, and we would apply ice to their legs for 30-minute sessions, significantly accelerating their recovery. I recognize the effectiveness of this method, yet the pain from the cold is unbearable. Should I endure this discomfort for longer periods?
Rash on My Arm: Should I Be Concerned?
Hi there! I’m a 65-year-old female, and for the past four days, I’ve been dealing with a strange rash on my arm. Unfortunately, I can’t visit a healthcare professional until Monday, so I’m hoping to get some clarity in the meantime. I’ll share some images. If they don’t upload here, I’ll post them in the comments instead. The first image, taken last night, is a bit out of focus, but this morning, the rash has appeared even redder. Although it doesn’t itch now, I did experience some itching during the initial two days. As for my health history, I generally don’t have major health concerns apart from elevated cholesterol levels and a recent A1C reading of 5.9, but I do not have diabetes. I keep fairly active for my age group. During the first couple of days, there was some pus, and I managed to clean it with an alcohol wipe, which helped remove it. Could this be related to a spider bite? I noticed some small spiders (specifically daddy long legs) in my bedroom, especially near the balcony door, and I eliminated a few of them today, so that could be a possibility. Should I be wary of any serious complications from this rash? Any advice would be immensely appreciated! My ER co-payment is quite steep, and there’s no urgent care facility nearby. My only option is to request an appointment with my primary care physician next week, but I’m uncertain if it’s something that warrants immediate attention.
