 [ Symptoms ] i take bentyl for stomach cramping and connection between that and leg cramps [ Disease ] common area no but herpes zoster shingles follows a nerve pathway so this painful infection can occur in this area hopefully your doctor prescribed the appropriate anti herpetic viral medications for you these are quite helpfu pain medication is also important since this can last a while longer how long it would not be possible to make an accurate prediction since this is really up to your immune system but i would expect that you would be considerably improved in a week if you had the antiviral medication the fever headache and flu like symptoms are typical of shingles so hang in there
