Swelling and Redness in Left Index Finger Knuckle Without Pain or Injury
I’m a 21-year-old male in generally good health, aside from my smoking habit. My family history includes cancer and autoimmune disorders. Recently, I observed that the knuckle on my left index finger, specifically at the proximal interphalangeal joint, started to exhibit pain. Interestingly, it’s the only area affected, characterized by redness and discomfort that emerged unexpectedly. A few hours have passed, yet the redness persists. I’m reaching out to the community for any thoughts or insights regarding this situation. Thank you!

It sounds like you're experiencing unexpected swelling and redness in your left index finger knuckle, which can be concerning. While you mentioned there’s no pain or injury, inflammation can still be an indicator that your body is reacting to something.
Main Points:
- Inflammation without pain or obvious injury can be due to several factors, including allergic reactions, irritation, or even conditions like inflammation from underlying autoimmune issues or gout.
- Your medical history and family background with autoimmune disorders might raise some considerations about the inflammation.
Explanation:
The swelling and redness at your finger joint can be caused by a variety of factors:
- Allergic Reaction: Sometimes, skin contact with certain substances can cause localized inflammation.
- Infection: Even without pain, there could be a mild infection or inflammatory response.
- Gout or Pseudogout: These conditions often lead to sudden inflammation in joints, sometimes without sustained pain initially; however, it usually occurs with other symptoms later.
- Autoimmune Conditions: Given your family history, conditions like rheumatoid arthritis or psoriasis could manifest symptoms in your joints, even with only mild inflammation.
Next Steps:
- Monitor Symptoms: Keep an eye on any changes in the swelling, redness, or if pain develops over the next few days.
- Rest and Ice: Apply ice to the area for about 15-20 minutes every hour as needed to reduce swelling.
- Elevation: Elevate your arm to help reduce swelling as well.
- Avoid Irritants: Stay away from any recent products (soaps, lotions, or jewelry) that may have caused an allergic reaction.
- Document Changes: Note any additional symptoms, such as changes in motion, new areas of swelling, or any signs of infection (increased warmth, discharge), which will help you evaluate the progress.
If the redness and swelling persist for more than a few days, increase, or new symptoms develop (like fever or spreading redness), consider reaching out for further evaluation.

Concerns About My Eye Condition
I'm a 19-year-old female, weighing 190 pounds and standing 5'5". Lately, I’ve noticed some troubling changes in my eyes. There are prominent, red veins extending from the inner corners of my eyes into the irises. Additionally, there are bright red streaks and pools forming at the lower part of both eyes beneath the eyelids, bordered by a yellowish hue. When I consulted two different doctors, they were unable to pinpoint the issue and simply recommended lubricating eye drops. Unfortunately, the condition seems to be deteriorating, with the redness spreading further. While there is no significant pain, keeping my eyes open feels like a struggle, and my vision has become increasingly blurry, leading to some headaches. I’ve been unwell recently, but I’m uncertain if this has any relevance to my eye problems. Any advice or insights would be immensely helpful.
Experiencing Numbness in the Right Arm or Leg?
Hello! I’m a 17-year-old assigned female at birth, weighing approximately 110 pounds and standing around 5 feet 2-3 inches tall. At the moment, I’m not taking any medications and I don’t smoke. Recently, I’ve been facing a peculiar issue where my right leg or arm occasionally becomes numb. This sensation only impacts my right side and never the left. It can occur at any time, both during day and night. Typically, the numbness in my leg arises when I’m lying in bed, although I also experience it randomly throughout the day. I’m curious if anyone has any insights or thoughts about whether this could be something more serious than just a problem with my posture, haha!
Concerns About Telemedicine during a Drive
Hello everyone, I'm a 28-year-old woman with a background of thyroid cancer, necessitating routine check-ups every six months. Recently, a question came to my mind regarding the professional conduct of my primary care physician. I was taken aback to learn that she participated in my telemedicine appointment while driving. I've noticed her appearing somewhat distracted during our in-person visits and at times, she forgets the medications we discuss during our reviews, but this situation felt even more inappropriate. It’s challenging for me to comprehend why I’m spending $450 post-insurance for what feels like a casual video call when it’s clear she is multitasking. Although I've been under her care for about two years, I'm eager to find a practitioner who will genuinely take the time to understand my health history and build a long-term relationship. I appreciate any insights you can offer!
Concerns About a Recent Lump on My Shaft: Seeking Guidance
I’m a 20-year-old male with allergies primarily to wood, pollen, and grass, which used to cause me hives, but that issue has resolved. Now, to address the main concern. I found a lump on my shaft while showering yesterday morning, and it caught me off guard. Up until now, I haven’t experienced any discomfort, and I still feel largely fine. The size of the lump is similar to that of a pimple or possibly a cyst, but I'm unsure. I'm contemplating whether it would be wise to consult a doctor about this issue, as I want to be informed on how to proceed. Any advice would be greatly appreciated!
Should We Handle This Ear Issue at Home or Seek Medical Attention?
I’m sharing this on behalf of my husband, a 33-year-old male who is not currently taking any medications and has no known chronic conditions. The only relevant detail is that he has a significant issue with earwax accumulation. At times, this leads to noticeable deposits on his pillow when he sleeps on his side, affecting his hearing. For the past few days, his ear has exhibited symptoms similar to what is often seen in various ear conditions. He reports feeling a sense of discomfort, although there is no pain or itchiness involved. Touching or tugging on the tragus and surrounding areas does not elicit any pain. He’s uncertain why there are scabs around this area. He mentioned experiencing a sensation of fluid inside the ear yesterday, prompting him to use some over-the-counter peroxide drops to help clear it out. He described the output as a thick, opaque discharge resembling earwax, but darker and more liquid in texture. Today, while the fullness sensation seems to have diminished, the discomfort remains. His other ear appears normal, perhaps just slightly dry, but nothing more than what is typical for ears. Given this information, I'd like to know whether this is a situation he can manage at home or one that warrants a visit to urgent care. Additionally, what might be the underlying issue?
