I Have Been On Acyclovir For Just Over A Year

I have been on acyclovir for just over a year for shingles of the eye that has chronically recurred. I also have symptoms of general body aches, flu like symptoms (achy, chills, nausea, no vomiting). I have had complete blood work up, UA, and X-rays. All is normal. I am also using gabaptin 300 mg at night. History of a fib, NIDDM, Crohns dz. could any one or both of these Ned's be causing my symptoms?
