My husband has been taking 2 carbidopa Levo every four hours for about 21 months for Parkinsons. About seven weeks ago he contracted Shingles and was given 2 Famvir 250 mg 3 times a day for seven days, along with 1 Cimetidine 400 mg 2 times a day, and Desoxametasone cream for the sores. After seven weeks he still has some infection, some nerve end are very painful, and he feels tired more than usual. Has anyone had any experience with PD and Shingles and do you have any suggestions? Thank you
