Post-Herpetic Neuralgia Treatments - Help!

Eye pain continues, can’t tolerate ANY drops in my eyes. Can’t take any pills due to ulcers. Does anyone with this type of TN get any relief from anything else? The prednisone helped a little with lymph node pain, but my eyes are only very slightly better, on occasion. The burning in my eyes is almost constant and I can’t really do anything. Can’t see my neurologist again until January 28, then will get test results. ANYONE GET ANY RELIEF FROM ANYTHING? i HAVE BEEN HOUSEBOUND FOR 6 MONTHS, I CAN’T TAKE THE COMPUTER, LIGHT, TV OR READING. I FEEL LIKE A NURSING HOME RESIDENT!!!
