Rheumatoid Arthritis Treatment

I am only 28 and learned of having ra 3 yrs ago. havent had any pain or problems in 3 yrs… now all of a sudden im in constant pain and have severe stiffness in my toes. is this normal? i was just curious if the summer heat and humidity may be playing a part in this

One of my family members has really bad rheumatoid arthritis (to the point where she can not get out of the bed some days) and I want to know what I can buy that would be of the most use to her.

Thank you SO MUCH for your help !
