and not want to come out of the attacks for hours
and that causes the nail splentors
and i even had a bad infection in one finger. I was sent to a rhumotologist to be dianosed with CREST. Sorry about the spelling!
I started the nitro glycerin patches about 3 weeks ago at 0.1 dose and stayed on that for 3 weeks and now i'm on the next step up 0.
