Hi Lobo,
Welcome to the board. I'm sorry you're so stressed out and frustrated about this, and I can't say I blame you. We get a lot of people here who have been given the runaround by doctors for HSV for a long time and we know how frustrating doctors can be about this stuff.
Just so you know: This board tends to be more focused on Herpes Simplex (HSV) than Herpes Zoster (shingles) and I personally don't know a whole lot about shingles. But the symptoms can be similar for both. I and hopefully others will help if I/we can.
The tingling sounds very similar to symptoms for HSV when it is active in the system (which may or may not produce a visible outbreak). HSV is chronic -- one treatment will take care of the current outbreak (OB) but there are almost always other OBs later. The one treatment won't affect those. I think the same is true for shingles.
Why did your doc ask if you were gay because you are having these symptoms?? That makes no sense to me. What do you think the doc was getting at by asking?
Have you ever had a blood test done for HSV? If tingling like that is not a typical symptom for shingles, you might try the blood test to see if you might have HSV as well, since that can be a symptom of that.
You might get some relief by going on antivirals again (I'm assuming that's what you were treated with before). Have you asked your doctor about trying antivirals again? If s/he isn't willing to at least give it a try to see if it helps, I think you need to find another doctor. Have you seen a dermatologist yet? Or a neurologist?
Sorry for firing all these questions at you but I'm trying to find a possible avenue you might not have tried yet, or which could be tried in a different way. I'll help if I can.
