Antivirals for long time

Hello, since August I have been on antivirals for a total of 90 days, first month Valacyc & after Acyclovir, when I stopped in Oct because I had a trip, and I was not feeling well, I felt better for 3 weeks and then started again the Acycl. I want to know your opinion on antivirals for this long or longer? It can be coincidence but my back muscles have bothered me a lot and recently I developed plantar fasciitis on a foot that I sparined but was better.
I am seeing a LLMD that believes I need to have my viruses under control, he understands that I am very sensitive to supplements, so I dont take much of them, the ones I have tried I wasted my money on them. Thanks on your opinion.

My LLMD has people take valacyclovir for months to treat chronic viral issues, and people with herpes type 1 sometimes take them for years to control outbreaks.

That said, antivirals can be very hard on the liver and kidneys; I would check on your kidneys as soon as you can if you are experiencing back pain. I also have read that long-term use of antivirals can damage the immune system, but I don't know the details about that.
