ive been expierencing "shingles" like expierences ( tingly on only one side, sweating profusely, excessive unintentional weight-loss and nerve damage, & unexplained lumps in my head) except 4 the tell-tale skin rash so that is leaving dr.s baffled...but it just hit me these were all the same things i did & expierenced thru my 1 yr of crystal meth addiction?...so i'm wondering if this is possible?
