On Dec. 7, 2010 I was diagnosed with shingles and began taking acyclovir 5 times a day. I am still taking it. I saw the nurse practioner who said I should take the medication as long as I had the tingling senstion at the site. I did not get in to see her within the 72 hour window that is recommended but I did get in before the blisters appeared which did appear 3 days after beginning acyclovir. I am still having some tingling sensations and sometimes bee sting like pain 2 or 3 times a day. Should I stop taking acyclovir and consider this the phantom pain that sometimes remains after shingles? Will these twinges get worse if I stop the medication?
