Hi there. I ve noticed a few months ago that I have a very sensitive scalp hurts when I put it up and it stay up a while. Hurts at my roots. Hurts just to touch in some areas. I also noticed the front part of my head above my forehead is thinning and very tender also that it s got a lump. We ll not really a very big noticeable one just one I can tell it s there about the size of a toonie but like I said no one else can really tell accept me. I have bad sinus s and they have been bothering me but I m on sprays. I find I get some tingling on my scalp. Their is no cuts, dandruff, etc just feels weird. I m worried I have a tumour or something. Please give me some advice
