I don't know whether I can get a cure at the end. I just put my struggling experience here in case it could be useful to the others. Please forgive my grammar errors since I don't have time or mode to correct them.
After taking DEC, this worm start to move from the backhead to forhead, and drill channels. it moved one inch each day from the side of my eye to my check, then make a twist to the ear. I felt strong pressure to the brain causing nauseousness vomiting. This is one of the most helpless moments I ever had. Going to the emergency room in the night would not be helpful since there is no short time to identify the worm, and no body is going to believe me.
Finally, my aunt came by and injected 10mL of Chymetin to my check next to my ear. Before doing the bulk injection she tested on my arm for 30min in case of allergy. My face was swollen temporarily. The injection process is a little bit pain because of the pressure of 10ml liquid. Then it was fine. It showed a channel from face to my ear-a tube shape swollenness. The swollen disappeared in 2 hours. I felt nauseousness and vomiting disappeared.
Chymetin was reported in Chinese paper that is to treat adult worms in the eye and face. I asked my aunt to buy them for me, and wanted to try them on my other parts of the body first (like leg,shoulder). Yesterday, it was urgent, then my face became the first place to try. I hope nobody else will have to experience something like this.
