so my sister's been having sore feet/hands for awhile and they went to get her checked out recently and last night found out she has arthritis. My mom has it and I can't think of my little sister getting to that stage. So my question is, are there any things she can do to kinda fight against it? notes: my mom has it, only 45 has bad case they found it late. has problem walking and hands are pretty bad. My sister is younger (16, nopics.), gets sick really easy takes vitamins for iron,etc. please help , i've been pretty beat up about it. She hasn't done anythign wrong ever and really does think about other people, and helps out.
