What Causes Rash On Legs, Fever, Bronchitis And Weight Loss?

About six weeks ago I had some unusual symptoms...rash on legs seemingly related to reaction to new tights...fever...bronchitis seemingly related to fungus in lungs....could not eat for days....lost about eight pounds...began to feel lighter and good. Afterwards my hair texture changed dramatically....went from feeling thick with plenty of body and easy to curl to sleek and lifeless. It does not feel like my hair anymore. I have continued to lose some weight and feel good but frustrated about hair. My e-mail address is YYYY@YYYY .
