FH are genetically weak fish, which is exactly why I no longer keep them. As to how best to proceed - your guess is as good as mine. Not all cases of prolapse will heal, some never will. If it was my fish, I would keep adding magnesium sulphate to the water, and his feed, but that's just me.
There is a TON of information posted here on MFK regarding the treatment of sick FH, some methods may work for your fish, some may not. Some medications may be available to you, some may not. No telling with any real certainty what your fish is dealing with, short of a smear/scraping, a quality microscope, and someone that knows what they are looking for, such as a qualified DVM.
Good luck
