Question: I've had a Petecial Rash for just over two months and it is slowly spreading. I first noticed a few dots on the outside of my left ankle and assumed it was from spraining my ankle or the wrap I was using. It quickly spread across both ankles (inside and out...outside is much worse) and up the shins and across the tops of my feet. After a month I had what I'm assuming was 5 days of unrelated morning chest pressure and elevated Blood pressure and went to a walk in clinic and the Doctor sent me straight to ER to rule out Endocarditis, Atrial Fibrilation and heart attack. ER didn't say much about the rash but said my EKG was fine and set me up to get a Holter test. (No results yet) .

Two weeks later my chest pressure was gone but the rash was still spreading so I went to another walk in clinic and the Doctor said it was Hemograghic (sic?) Purpura. He ordered a CBC with Differential and a Pt-INR test and said "we need to find out why you are bleeding". I saw the results online and they seemed normal and the Doctor never called so I'm assuming I read the labs correctly.

I went back to the first Walk in Clinic this past week and a 3rd Doctor called it a Petechial rash and order CBC w. Diff, a CRP test and both a Pt-inr and an aPPT test- again, everything looks fine from what I could tell. He also swabbed the area and labs came back normal (from what I read). I'm seeing a Dermatologist in January but just thinking if something was wrong it would have shown up on these tests. Today, it was up my left thigh and on both biceps and is still really bad on my feet, ankles and shins. Other than swollen lymph nodes for the past month I'm pretty much healthy and don't feel sick. No fever or aches. I had a few months of bad night sweats in the late spring and Summer (despite having the coldest and best air conditioner) but that went away. I'm in decent shape but I smoke, age 44. Zoloft is the only prescription and I've been taking that since 2002. I don't have a Family Doctor since moving.
All of the Petechiae is flat except the ones right behind my ankle, those you can feel. I assumed this was vasculitis but my CRP was .7 out of a <5 range. Any thoughts on why this is suddenly occurring after 44 years? Should I bother going to the dermatologist?
