Hi chyuu: I'm not sure what you mean. Is it that you really do get everything out, and it still feels like you have to go, or is is that there is a stool still stuck?If it is a stool that's still stuck, I get that if I take a pain pill like tylenol, midol, or especially a prescription like fuorinal or tylenol III, etc. A stool will be 1/2 way out, and it won't come out. Don't strain or push, though as that causes hemmeroids, and for me, if I push, it will for sure be a lost cause. The only solution is an enema.If you really do get it all out, and it still feels like you have to go, you may have a spastic colon. I've had that (IBS-C) for 35 years and know the feeling well. If you are "regular" that feeling will go away. The trick is to get regular.
