I have had a burning mostly prickly pain for about 10 months now, my GP has had and run numerous tests to no avail. I have had scans, MRI s ultrasounds, everything, Cannot find the cause. I think it is shingles on the inside, I have no evidence of it on the outside, but it is just the torso on one side of my body, since I had the chicken pox as a child, he says there is no way to test for them on the inside. This is maddening to say the least. Can the antibiodic for shingles hurt me if I don t have them?
