Hit head hair loss and burning scalp

About 6 months ago, I was leaving my fiance's house and hit the left side of my head really hard on the low overhang of her front door.  I didnt think anything of it at the time because there was no redness, swelling or cuts, bruises, etc.  A few weeks later, I was taking a shower at work and when I got out I looked in the mirror and my hair appeared dented in on that side of my head, almost a lopsided look. As time went on, I started to get a burning, tingling sensation on that side of my head that spread to the back of my head as well. My hair started thinning on the whole left side of my head, even in the very back of my head. I still experience burning sensations on that side to this day and my hair hasnt gone back to the way it was. Just last week, I was folding clothes in my spare bedroom and hit the middle right side of my head on a low light fixture and now I am experiencing the same sensations on that side and it really scares me! I am gonna lose all of my hair because I barely bumped my head on something?? I mean, really? Im very frustrated and have been online looking for answers. The only thing I can find is that it is maybe Tellogen Effluvium, Scarring Alopecia, or Burning scalp Syndrome. I really dont know. I have an appt with a dermatolgist in 2 weeks but would like an opinion from someone on here if possible. Thanks.

Hello,
First of all this bumping of the head is not related to your hair loss. Telogen effluvium is a probable diagnosis Other causes include alopecia aereata, hormonal imbalance(overproduction of dihydrotestosterone and thyroid hormones irregularities),malnutrition, telogen effluvium and sebum plugs on skin.

I would suggest you to consult a dermatologist and get these possibilities evaluated.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
