Yeah, it's possible.  You know tx was going so smoothly for me before
the rash.  Just mild muscle aches and tiredness and maybe a little
emotional thing.  No nausea, headaches, or anything else.   Shots were
never a factor and seemed irrelevant.  I battled with a nasty rash for
about a month that had its ups and downs.  Some days I had it under
controll.  Finally woke up with a swollen face and got called in to
check it out.  Found my lymph nodes swollen and they said the rash was
much worse than they've seen.  They say I need to be admitted to the
hospital because they don't know what to make of things.  The docs in
the hospital immediately take me off the meds.   Two days later the
dermatologist says my rash is consistent with a drug induced reaction.
No one knows which drug caused it.  My skin is still healing from that
last ordeal.  Still talking things over with the GI doctors to decide
whether I'm done.  They said that ibuprofen can be associated with
rashes and reactions.  On my bottle it says Allergy alert:  Ibuprofen
may cause a severe allergic reaction which may incluse: *hives *facial
swelling *asthma *shock.  That one about the facial swelling is what
really makes me think.  I think you're right about the PCR though.  

Thanks Michael.  One part of me feels the same.  The other wants more
info.  One thing that is for sure is no more ibuprofen for me.

Aw jeez, care to elaborate?  I'm on 40mg per day of prednisone now
trying to clear up a skin problem.  I fear corticosteroids.  Even the
topical ointments.
