for the last few years i have been getting rashes that won't heal completely. it seems they get worse with bug bites, certian foods like black pepper and stress. it forms around my mouth, arms, hands, back of neck and now my legs and some times stomach. always always on my left pinky finger to where the skin usually breaks and becomes swollen and i feel heat rush to the spots with my heart beat. no one seems to have an answer other that steriods. and solodyne which do not help anymore. the first rash i got was on my left leg after my acl replacement. could that be causing an immune hypersensitivity? my histamine response is in over drive. please help!
