Oxy…yikes. Hope you can get off that. I can't take 600 mg. gabapentin either so I take 200mg morning and 200 mg evening. I also now, after 9 years, have a topical compounded cream to apply several times a day to my forehead, eyebrow area. I went to a pain management anesthesiologist and he had this put together for me. It contains lidocaine, gabapentin and several other drugs. For several years my eye didn't dilate properly and that led to extreme light sensitivity. Your symptoms may go away at this point. Most do. Only a few of us have years of problems. In my case, I wasn't diagnosed & put on anti-viral promptly. I had a severe headache and no blisters until the fourth day.
