He could touch places on my face with a cotton ball and get the pain to happen. He gave me a drug Tegratol ànd I t is helping àlot a!most gone now. How long does it take for this medicine to cure this? It is not bad but makes me a little wobbly and things seem to look a little funny or something. It is hard for me to say what it is. Thànk y'all for letting joiñ and for helping me. Mini
