i AM 54 244LBS. HAVE HIGH BLOOD PRESSURE AND PRE DIABETIC TAKE METHYLDOPA 500 MG 3 X DAY AND METFORMIN 500 MG 2 TIMES DAY/

I developed rash that itchy and red on hands, when scratch gets worse. skin pealed viscous cycle for 2 weeks went to dr and got steroid 20 mg 6 5 4 3 2 1 and all cleared up and went away. within 2 days of finishing steroids came back with now worse new rash more rash each day spreading all over my hands . new rash on tummy, back of neck and under arm. Lymph nodes under arms are painful. Too dyflucan (yeast pill yesterday but not change , if anything rash spreading morr on hands.) skin burns or tingles before new rash.

rash is red bumps they turn inot ptach and eventualy have whte dry skin on top.

now wondering if it is metformin or arthritis or what could it be? gp said if since cleared up with steroids then came back said i should go to dermetologist. sons ses ansays looks like althetes foot on main finger
