My 80-year-old father has shingles on his head, face. Mostly the redness on the skin has left, but it's in his eye & driving him crazy. Doctors have given him eyedrops (Valtrex?) & pain meds, which give him hallucinations. Has anyone had experience with treatment after Valtrex and eye medication? Or pain control other than opiates? Alternative treatments? Any help would be appreciated.
