That is hard to predict since we are all different, but you have a good chance that you will feel better, the only thing is that it might come back till you have done several flushes.

If you want to run a test, drink a glass of water with 2-3 tsp dissolved Epsom Salts (=magnesium sulfate), normally the pain will go away in 15-20 minutes. This not a cure but it will give you some feeling what the flush will do.

So do the flush Sunday and do one every 2-3 weeks.
