After the 1st 3 pills I already have pain in my stomach, and pain in my muscles every part of my body in different time. I feel so tired I want only sleep and the thing which I really worrie about I’m having pain in my back probably I feel my kidneys. I’m really care about my health and now I have no clue what to do. Should I stop to taking the aciclovir or should I continue because of to not to get more blisters? Is there anyone who had similar problems?
