Hi,I don t know what I have but I m getting worried.. I had an accident almost years ago that caused some brain damage .. I have TBI..almost all my problems started then...My Neuro , is still trying to find out what causes all my setbacks.. lately, the past 4 months I have broken out in a itchy rash on my face, neck , chest, stomach, legs, & back..at first thought I was having a allergies reaction to something or my medicines that I am taking for my head pain or a infection of some sort.....My reg Doctor & Allergy Dr ruled all that out.. I started getting needle like pain in my hands & feet .. My whole body is swollen..I m on Lasik s right now and it was helping at first but now it s not... Im a far skin person.. I ve only got some sun twice this year.. At first when I broke out with itchy bumps all over I looked like a had a dark tan & red.. My hands & feet would change red, blue or yellow..now its ll over my body and my veins are very noticeable... My arm pits are swollen and so is the back of my head...I m thinking that is my lymph nodes... back right side of my head has been swollen since my accident..so I don t know if this connected with what is going on with me now... I dont know if me seeing two of everything is connected to this too.. I saw the eye doctor.. he said it has nothing to do with him & I need to go back to my Neuro doctors... My reg Doc did find out that I do have Reynaud s Phenomenon.. Cancer runs in my family.. most all my family that passed died of some sort of cancer... Could this be cancer or a tumor somewhere?
