Unusual Mark on My Neck After Sleep
At 22 years old, I am not currently on any medications and have no diagnosed medical conditions. After only three hours of sleep, I discovered an unusual mark on my neck upon looking in the mirror. This mark does not resemble a scratch; its color and texture are reminiscent of a hickey, yet it is neither painful nor elevated. It does not conform to the shape of my neck and has persisted for over five hours since I woke up. I do not have pets and do not share my bed with anyone; although I live with housemates, my door remains locked, making it unlikely that anyone else caused this. I haven't engaged in any strenuous activities today, nor do I usually wear clothes that are tight or any necklaces. I'm feeling a bit anxious and would consider visiting a doctor if this issue persists. In a post I shared, I noted that the mark is somewhat U-shaped and there are additional markings located beneath my chin. A friend joked that it resembled a bite mark, which only heightened my concern.

It's understandable to feel anxious about an unusual mark on your skin, especially when it appears suddenly. In your case, the mark that resembles a hickey but is not painful or elevated could have several benign explanations, such as a benign reaction to pressure during sleep or even a skin condition. The absence of pain, elevation, or any signs of infection such as warmth or pus is reassuring.
Explanation
Marks that appear on the skin can result from various non-serious causes. For example, depending on your sleeping position, you might have inadvertently pressed against your bed or pillow in a way that caused a temporary bruise-like appearance. Other possibilities include skin irritation or a reaction to laundry detergent, fabrics, or even a minor insect bite that has since faded. The U-shape and additional markings you've noticed could also be consistent with how pressure was applied to your skin.
Next Steps
- Monitor the Mark: Keep an eye on the mark for any changes in size, color, or texture over the next few days. Take note if it starts to itch, becomes painful, or shows signs of inflammation.
- Gentle Care: Avoid scratching or irritating the area. You can apply a cool compress if it feels uncomfortable.
- Document Changes: Take photos daily to track any progression or changes in the mark's appearance. This can be helpful if you decide to consult a doctor later.
- Stay Calm: Anxiety is a normal response to unexpected health changes. Try to focus on self-care, such as relaxation techniques or talking to a friend about your concerns.
If the mark does not improve in a week, changes drastically, or you develop additional symptoms (such as fever or extensive swelling), it would be wise to consult a healthcare professional for peace of mind and further evaluation. Please remember that many skin marks resolve themselves without intervention.

Is My Newborn’s Head Shape Normal?
My son is currently 5 weeks old, and I’m feeling a bit anxious about his head shape. We have been incorporating brief sessions of tummy time into his routine each day. I also make an effort to carry him over my shoulder frequently and switch sides when laying him down in his crib. However, I can’t shake off the worry that his head appears to be flat. It concerns me greatly, and I feel like I might be letting him down. He is being fed with a mixture of breast milk and formula from bottles.

Sore Bump in Armpit Area
Female, 41 years old. No ongoing medications. No previous medical conditions noted. I underwent a complete hysterectomy on May 7, which marks my significant medical history. For the past few days, I've experienced discomfort in my armpit, but there were no visible signs. However, a small bump appeared last night, and it seems to have enlarged slightly by this morning. I made sure to mark it in the photo I took. I opted not to apply deodorant today and chose to wear a loose-fitting shirt. The area feels tender without any pressure, and it becomes quite painful when I touch it. Currently, it doesn't feel warm to the touch. I am trying to remain calm, especially since it is on my left side. Can anyone offer suggestions about what this might be? I am considering a visit to urgent care after work.
Bright Red Blood During Bowel Movements
I’m a 27-year-old female, weighing 157 pounds and standing at 5’3". I have no significant medical history, nor do I use drugs, smoke, or drink alcohol. My only medication is Paxil at a daily dose of 40mg for anxiety. Today, I experienced a bowel movement, and upon wiping, I noticed bright red blood. It wasn’t mixed with the stool itself. Following the bowel movement, I felt some soreness inside my rectum. A few days earlier, I had a particularly difficult bowel movement that was hard to pass. As of now, I haven’t experienced any additional symptoms, but I am extremely worried that it might be a sign of colon cancer.
