Scalp pain, burning and shedding

[briggscreek]

I'm 33 years old and have always had very long, thick hair. In fact, just a few months ago I was thinking how thick and healthy my hair was. I have been having increased shedding within the past few months and my scalp started constantly burning like it's on fire. I've seen my dermatologist and they see nothing wrong with my scalp, just gave me some topical steroids which have done nothing. Both my derm and primary doc have told me that the burning likely has nothing to do with my hair loss but I don't believe it. I don't know what to do, I've had tons of blood work and was told everything is normal. I don't know what to do at this point, I'm in constant pain and feel like I'm losing it. I would also like to know what the actual average daily hair loss is since my docs tell me it's completely normal to lose 100 hairs a day. If I lost 3000 hairs every month and new hair grew only 1/2 inch, it would obviously result in thinner hair. My hair is noticably thinner to me.
