I get flank pain (usually on left side, but occasionally on right) whenever I on a chair for more than an hour. No other postures hurt. Is this something to be worried about?
Mostly mechanical pain due to muscle tension. If no other symptoms then don’t worry.
Don't worry brother.This pain is due to spasm of skeletel muscles.Take some analgesic and some muscle relaxent after meals. Try to avoid some specific posture that causes pain.
