What are your intentions? Do you want to stop using or just get the pain to stop? Do you think that the pain is coming from snorting the drugs? Those as you know are powerful pain reliever's and from here it seems like once you take a hit, it deadens the area's it goes to and when it wears off the pain returns. This can't go in two many different directions at this point. Did you read the other posts from the other post you made about the saline spray? It sounds like it will burn, but you have to do something and soon. To me it seems your going to have to see a doctor and get him on board with you. The face pain sounds like the sinus's, probably the same cause. Most of us have reached " a point" and a time when it's time to quit. You know continuing this will get worse, fast. Keep posting on this post so we can watch for you, ok?
id slowly stop doing it, idk, i dont have experience with snorting pills just eating them, but someone here will help you :) its slow on weekends xoxo
