Dark Growth on Thumb Accompanied by Redness
I'm a 28-year-old male weighing 210 pounds. Approximately ten days ago, I noticed a red patch forming on my thumb. Initially, it presented as merely a reddish area before gradually developing into a bump after a few days. At first, the bump was relatively light in hue, but as time passed, it began to fill with a substance and took on a yellowish tint. Now, it has darkened significantly, nearing a black appearance. While the size of the red area and the bump has remained consistent, with no signs of expansion, the color continues to evolve. There is no discomfort when the red area is untouched, yet any accidental contact with the bump can provoke some pain.

It sounds like you're experiencing a concerning change on your thumb that has evolved over the past ten days. The key points here include a red patch that developed into a bump, which is now darkening and showing signs of inflammation. It's good to be attentive to changes in your body, especially when it involves your skin.
Explanation:
The symptoms you describe—starting with a red patch that becomes a bump and darkens over time—could indicate various conditions. Potential causes include skin infections (like an abscess), cysts, or inflammatory skin conditions. The absence of overall pain but mild discomfort when touched is important. However, the darkening and changes in color could signal something that requires further evaluation.
Next Steps:
-
Monitor Symptoms: Keep track of any additional changes. Note if the bump becomes more painful, if there is increased redness, swelling, or if you develop fever or drainage.
-
Avoid Irritation: Try to avoid touching or irritating the bump to minimize discomfort. This includes avoiding tight clothing or any potential friction on that area.
-
Maintain Hygiene: Gently clean the area with mild soap and water. You can apply a clean sterile bandage if needed to protect it from further irritation or contamination.
-
Consider Over-the-Counter Pain Relief: If the area becomes more painful, consider using over-the-counter pain relievers like ibuprofen or acetaminophen, following the instructions on the label.
-
Document Any Changes: Keep a log of your observations regarding the bump's appearance and any associated symptoms. This will be useful if you need to consult a healthcare professional later.
If the bump continues to change, shows signs of infection (like increased warmth, spreading redness, or drainage), or if you develop new symptoms, it's advisable to seek medical attention as soon as possible for a thorough evaluation and appropriate treatment.

One Week After Surgery and Experiencing Bleeding
Hello everyone, I wanted to share my experience following a procedure I underwent on June 13th. I’m a 31-year-old female, and during this surgery, I had a hysteroscopy along with the removal of some polyps, a biopsy, and diathermy performed on my cervix. Interestingly, I was on my menstrual cycle when the surgery took place, but my bleeding stopped for a while. Now, exactly eight days post-operation, I've started bleeding again and am also feeling some cramps. Could this be my period returning, or might it signify another issue? Should I reach out to my OB/GYN for further advice? I appreciate any insights. Thank you!
Is It Normal to Feel This Way After Being Ill?
Hello everyone, I'm a 34-year-old male, and I've been under the weather for almost two weeks now. Getting sick isn't something I'm used to, so the duration of this illness has me worried. Below is an outline of my symptoms and where I stand at this point. It's worth mentioning that I've not experienced any fever during this time. **Days 1-6:** - I experienced a headache primarily on the right side of my head, particularly around the temple area, which sometimes extended behind my eye and around my ear. - By the sixth day, I began to notice occasional pain in my ear. - I also encountered a couple of episodes where my left cheek felt numb after taking ibuprofen, but this only lasted briefly. **Day 7 (Doctor Visit):** - Upon examination, my doctor noted a red throat and swelling in my right ear, leading to a diagnosis of an ear infection. - I was prescribed Azithromycin and Methylprednisolone. - Although the headache continued, it was less severe compared to previous days. **Days 8-11 (After the Appointment, While on Antibiotics and Prednisone):** - The headache gradually improved over the next few days, but it hasn't completely disappeared. - I feel some weakness in my upper back and neck; my head feels heavier than usual. This has improved slightly but remains noticeable, especially in the evenings. I tend to wake up feeling just okay. - While my neck is strained albeit not painful, I can still move it without restriction. - I have mild sinus pressure right above my cheek on the right side. - My energy levels are low, particularly in the afternoons and evenings. - There’s a sense of weakness in my arms and legs, though this has also improved and isn’t my main concern anymore. - I had moments where I felt feverish, but I didn’t have an actual fever. - Every so often, I experience a throbbing sensation in my head, neck, or back. **Days 12 and Beyond (Current Condition, First Day Off Antibiotics):** - Occasionally feeling feverish again, but still no fever detected. - A mild headache remains on the right side. - Sinus pressure continues above my right cheek. - My neck feels slightly strained, yet it's not painful and I maintain full mobility. - The area from my mid-back to the back of my neck feels uncomfortable at times, with occasional throbbing but no pain. - I generally feel like I am still battling this illness. I understand that the effects of Azithromycin might last for another four days, but I’m anxious about not feeling even close to 100%, or even 80%, better. I'd appreciate any insights or advice you might have.
Rash Concerns for My 2-Year-Old Daughter's Right Hip
For the past six weeks, my little girl has been struggling with a rash on her right hip. We’ve sought advice from both her pediatrician and a dermatologist, but they seem to be at an impasse, debating whether the cause is viral or fungal in nature. We recently completed a two-week course of steroids, which unfortunately did not lead to any significant improvement. Interestingly, the rash did transform, appearing quite different than before. Following her latest consultation with the dermatologist, she has now started a treatment regimen with griseofulvin, as the focus has shifted back to a potential fungal infection. It would be helpful to hear a second opinion on this matter. She occasionally complains of itchiness, and when the rash is accidentally scratched or touched too roughly, she cries out, expressing discomfort. Any insights would be greatly appreciated!
Burn Recovery Update: How's It Healing?
At 28 years old, I've sustained a couple of second-degree burns, and I'm seeking some feedback on my healing progress. Today, I've been using an over-the-counter silver ointment for treatment. To clean the affected area, I've been gently dabbing it with a mixture of lukewarm water and Irish Spring soap, always making sure to handle it delicately. During the initial two days post-injury, I didn’t realize that I needed to give it attention; however, I must say it hasn't caused me any pain since the injury occurred. Throughout the day, I suspect I might be experiencing some form of a placebo effect, as I've been sensing unusual sensations, but overall I'm curious about your thoughts on my condition given these updates. How’s it looking so far?
Understanding Lingering Head and Neck Pressure: Seeking Insights
At 20 years old, I’ve been dealing with a nagging sensation of pressure in my head and neck for roughly three weeks now. This feeling is bothersome and occasionally triggers headaches, though it doesn’t occur all the time. The pressure resembles what some individuals report experiencing during shifts in weather or when it rains, but my discomfort arises randomly, even when the weather remains pleasant. Additionally, I often feel an urge to pop my ears, despite there being no actual need. I struggle with poor posture and tend to sleep in a very curled position, reminiscent of a fetus, tightly wrapped around whatever soft item I’m cuddling. As a result, I commonly wake up with neck and back discomfort; however, I’m unsure if this is connected to the pressure. It’s worth noting that these symptoms seem to intensify after lengthy gaming sessions that can last anywhere from two to five hours. Moreover, I have obsessive-compulsive disorder (OCD), and since this sensation has persisted for a noticeable duration, I’m beginning to fixate on it, which is causing me considerable anxiety.
