Identifying a Mysterious Brown Circle on My Scalp
Age: 21 Gender: Female Height: 5'4" Weight: 175 lbs Ethnicity: White (Scottish/Irish) Location: California Current Medication: Testosterone injection administered subcutaneously in the thigh While I was having my hair dyed blue, my girlfriend noticed a perfectly circular brown mark on my scalp. It resembles a circle that appears to have been made with a brown marker. The size of the ring is similar to my thumb’s tip and contrasts sharply with the lighter shade of my scalp. There is no evidence of hair thinning or loss around this circle; we only discovered it because we were parting my hair. I’m curious if this could be connected to the brain fog or headaches I’ve been experiencing lately. I looked online, and while ringworm was suggested, it doesn’t match my symptoms since there are no bald patches or flaky skin. I’m open to answering any additional questions to help clarify this situation, as it's causing me some concern.

A perfectly circular brown mark on your scalp can be concerning but it may not be directly linked to your brain fog or headaches. This type of mark could result from various benign reasons, such as a skin condition, a harmless mole, or even a reaction to the hair dye. It’s important to monitor it for any changes in appearance, size, or associated symptoms.
Explanation:
- Types of Skin Marks: The brown circle may be a benign nevus (mole), seborrheic keratosis, or even a reaction to your hair dye. Ringworm would typically present with redness and flaking, which you don't seem to have.
- Connection to Symptoms: While your brain fog and headaches are valid concerns, they might not be directly caused by the skin mark you're noticing. However, if you're experiencing persistent headaches or significant changes in cognitive function, it’s essential to evaluate those separately.
Next Steps:
- Monitor the Mark: Keep an eye on the brown circle for changes such as:
- Size or color alterations
- Unusual sensations (itching, pain)
- New symptoms appearing around it
- Skin Care Practices: Avoid harsh hair products or dyes on the area and keep the scalp clean.
- Symptom Journal: Track your headaches and brain fog, noting frequency, intensity, and any possible triggers (e.g., stress, diet).
- Consider Professional Evaluation: If the mark changes, or if your cognitive symptoms worsen or persist, ultimately it would be wise to seek evaluation from a healthcare provider for a thorough assessment.
It's understandable to feel anxious about new symptoms, so prioritize monitoring while ensuring you take care of your overall health. If you have further questions or notice any changes, don’t hesitate to ask for guidance again.

Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.

Experiencing Heart Palpitations Following Chest Impact
I'm a 17-year-old female who has struggled with tachycardia for several years, having been diagnosed with postural tachycardia syndrome (POTS) about five years ago, although I haven't pursued further testing because I haven't completely lost consciousness. Recently, over the past month or two, I've started to experience sensations of my heart skipping beats, accompanied by difficulty in breathing during these episodes. These occurrences have become significantly more frequent, even when I'm at rest. Five years ago, I underwent a Holter monitor test, which indicated primarily tachycardia with occasional premature ventricular contractions (PVCs), but nothing alarming was found. In early December, I was struck hard in the chest by an elbow while in a mosh pit, which resulted in some pain when taking deep breaths for a few days. My sternum became bruised and slightly swollen, and it remained tender to touch for about two weeks, but this discomfort was manageable. I still feel some soreness when stretching, although it’s not severe. Additionally, I have diagnoses of Crohn’s disease and hypermobile Ehlers-Danlos syndrome (HEDS), and I am currently on immunosuppressants. Given these circumstances, would it be advisable for me to seek medical evaluation, or could these symptoms be considered typical?
Post-Gallbladder Surgery Concerns: Potential Infection Three Weeks Later?
Subject's Age: 35 Gender: Female Height: 5 feet 4 inches Weight: 160 pounds Ethnicity: Asian Duration of Symptoms: Last Three Weeks Geographic Location: United States Relevant Medical History: Almost three weeks ago, I underwent gallbladder removal surgery. In the last few days, I have observed a small amount of cloudy discharge emerging from my incision site. Recently, I noticed what appears to be pus leaking from the area. While there is no significant pain, I do feel a mild soreness when I touch or move the site. I have not experienced any fever or chills, and there’s no unpleasant odor coming from the wound. Should I continue to clean the area with soap and water, or is it advisable to seek medical attention at the emergency room for further evaluation?
