Persistent Unexplained Lesion on Inner Thigh
At 24 years of age and female, I have been dealing with what appears to be a minor blood blister located on the inner part of my lower thigh for approximately four to five years. This lesion tends to appear and disappear over time. Occasionally, it resembles an empty blister, only to later expand slightly and appear filled with a dark liquid. When it reaches its largest size, it is comparable to a Tic Tac and has a slight elevation. Although it does not cause any pain, I can feel its presence as I walk, particularly when my thighs come into contact with one another. Furthermore, I wish to note that recently there has been the first instance of some redness surrounding the area. I will provide additional details in the comments.

It's understandable to be concerned about a persistent lesion, especially one that has been present for several years and has recently changed. Here are the main points regarding your situation:
- Observation and characteristics: Your lesion has been stable for several years but has recently presented with surrounding redness, which is a new development.
- Potential causes: The lesion could be a benign issue such as a venous lake, an inclusion cyst, or a benign vascular malformation. However, changes in color or size may warrant closer attention.
Explanation
The fact that your lesion has been present for a long time without significant discomfort is reassuring. Blood blisters can form from minor trauma, while surrounding redness might indicate irritation, inflammation, or even an infection. It’s essential to observe any changes closely.
Next Steps
-
Monitor the lesion: Keep an eye on any changes in size, color, or if it becomes painful. Take note of how often the redness appears and if it changes with activities.
-
Self-care measures:
- Avoid unnecessary friction on the area (e.g., wearing loose-fitting clothes).
- Keep the area clean and dry to reduce the risk of irritation and infection.
-
Document changes: Take photos of the lesion over time to track its appearance and any changes.
-
Be alert for signs of infection: If you notice increasing redness, warmth, swelling, or pus, these could indicate an infection, and it's advisable to take further action.
-
Seek further evaluation: If the lesion continues to change or become bothersome, consider seeking evaluation from a healthcare provider, especially if it doesn't resolve or worsens in the next few weeks. They may recommend imaging or a biopsy for a definitive diagnosis.
Please feel free to share any additional details or ask further questions if you have more concerns about this lesion.

Concern for My Health: Seeking Answers
As a 37-year-old male who smokes and has a history of bipolar disorder (BPD) and memory problems, I’ve recently faced some alarming health issues. Initially, I felt fine, but a few months ago, my condition took a sharp turn. I began experiencing debilitating headaches, neck pain, and an unsettling stiffness throughout my body. I also noticed an uncomfortable sensation where my skin felt like it was burning, as well as issues like oral thrush and mouth ulcers. Cognitive challenges surfaced, including brain fog and confusion. I felt emotionally detached, and my genital area became painful to the touch. Additionally, I experienced soreness in my legs and arms, making it difficult to climb stairs. Alongside these symptoms, I was suffering from night sweats and had trouble sleeping. Most concerning was a sudden flare-up in my genital region. My doctors suggested that it was herpes, a condition I’ve dealt with for years. Thus far, I have undergone significant medical evaluations: I spent three days in the hospital due to intense headaches, where I had extensive blood tests, a CT scan, and a lumbar puncture. I visited a sexual health clinic two weeks prior and had to wait for a retest because my initial blood work fell outside the relevant timing. Fortunately, during my hospital stay, all tests returned negative and my results were normal, which leaves me more confused. Despite these clear test results, I feel like I'm falling apart and struggling to maintain my sanity. I’m reaching out for any insights or ideas that might help illuminate what I might be experiencing. Thank you for your time and assistance.
Experiencing Lip Numbness Following General Anesthesia
At 29 years old, I've recently undergone a surgical procedure on my head, and now I've noticed that only part of my lower lip has become numb. After contacting the hospital ward, the doctor reassured me that this numbness is unlikely related to the surgery itself; it might instead stem from trauma caused by the intubation during the procedure. I’ve checked my lip thoroughly, and there's no visible skin damage or any noticeable changes—it's just a complete lack of sensation. The doctor advised me to visit the emergency department should my symptoms not improve, yet I’m uncertain if my situation truly qualifies as a medical emergency. Is experiencing this kind of numbness common following such procedures?
Bilateral Finger Numbness
A 46-year-old male, who smokes, weighs 77 kg and stands at 6 feet tall, consumes beer occasionally and has a diagnosis of ADHD. His current medications include Elvanse at 70mg, pregabalin at 600mg, and venlafaxine at 150mg. In the past year, he underwent a series of extensive tests for fatigue, which included assessments for B12 levels, iron, glucose, and vitamin D. These led to the use of a CPAP machine. For more than a year, he has experienced mild numbness in his fingers. Recently, he took up a cleaning job, and in the last three months, he has noticed that the numbness in his right hand has intensified, affecting his thumb, index, and middle fingers. Meanwhile, his left hand shows significant numbness in the ring and middle fingers, which paradoxically have areas of heightened sensitivity—any slight impact or pressure causes noticeable pain. He struggles increasingly with hand functionality, often dropping items and finding it difficult to perform tasks such as opening jars or fastening buttons. There is also a notable weakness in his non-dominant left hand. Initially, he suspected that these symptoms were related to carpal tunnel syndrome but now questions the likelihood of both hands exhibiting similar issues, especially with the left one deteriorating more rapidly over a short span of three months. With an appointment scheduled with his general practitioner on September 3rd, he is contemplating whether he should seek another opinion sooner. Thank you for any insights you can provide.
