Hi. I am a 22 year old female. I just recently noticed a vertical indentation from the very top of my head down maybe an inch of my crown. It doesnt really hurt, but because I have been touching it a lot and allowing family members to feel it, it seems a little soar or sensitive now. I just got my hair dyed last week where I sat under a heater for a while. I have not had any injuries, but I have always had crazy allergies. I wake up nearly every morning with a runny nose, congestion, and sometimes a sinus headache. I use to get allergy shots once a week for a while, but that was years ago. I have also lost about 10 lbs, I have been trying to eat healthier and exercise. But this past week or 2 I have been eating junk food.  What is this seemingly sudden indentation on my head? Should I be concerned?

### output:

Hello Dear!  Thank you for asking. I read your query and I want you to know that if the indent on your head is not proceeded by some trauma or fall then it is probably innocuous, and it will go away. If it doesn't in a week you can see Nearby GP to assess this bump and sort out the etiology for you. If it hurts simple acetaminophen or topical NSAIDs will be enough. Now your main Concern.
