It depends on the degree of rheumatism one has. If you have mild rheumatism,
cupping can be advantageous for some and may provide some relief. However, if you
have severe rheumatism with very tender and swollen joints, cupping could potentially irritate the condition due to the inflammatory state. So, it is best to try it gently and observe how your body reacts. Adjust the suction of the cups so that you don’t place them on the highest setting immediately; attach them softly and cautiously. If done moderately and not too forcefully, it usually doesn’t cause any problems. However, start gently and pay attention to how your body responds since it can vary
from person to person. It also depends on your overall health condition. If you’re unsure, consult with your doctor beforehand.
