Hi for the last 3 days i have been having pain in my low right back, where i supposed my right kidney is. It hurts but the pain feels like a bruise. I havent fell down or knocked on to anything so i dont know why i am having this pain. I have checked and see a small bruise but the pain seems too much for the small bruise. I recently started going to the gym
Hello and Welcome to Chat Doctor, Thanks for writing to us. Your lower back pain and small bruise seems to be due to muscle strain might be while doing exercise in Gym. I suggest you not do exercise that involve painful muscle for some time. Take rest. If bruise persisted for long time or another appeared without reason, get it evaluated by physician. Hope this helps you. Wishing you good health... Regards.  Chat Doctor. Orthopedic Surgeon.
