PG how bummed I am to hear the patch isnt a help for you.
I do know that before i could even be considered for my stimulator implant i had to be on every med they had and have the med fail ..I had to reach the end of the med line before any other option was offered. as i siad I had option of morphine pump implanted in back of head only the morphine didnt help one bit by then i was suicidial and it was either doc help or i end things.cus I was not going to live i couldnt live another month like i was. NO JOKE! keep searching and trying and know you arent alone. do not give up on o.n.s. red tape is thick it takes a bit of cutting and sawing to get threw be persistant and patience!! hang in there my friend .
have you tried a bath with baking soda or epsions salt?
praying your allergic reaction and rash go away a.s.a.p.
and that good things begin to happen for you this month.

PEACE
