Brother. I do not have RA but do have regular arthritis which is way easier to manage. Though when it flares up my hands hurt and it is hard to manipulate things like even text. RA makes training hard, both in the gym or at the camp. When I spar I always tell my partner no more than 75% and sometimes light touch sparring to save my hands (and my head) We have a sauna at my gym. After working out I sit in the sauna for 20 minutes then go home and turn the water on cold. I hop in until I cannot stand it. It sucks but seems to really help.

My sis has RA real bad. She is doing the anti inflamatory diet and it has helped her a lot.

Best wishes.
