Why Could There Be Constant Discomfort Around The Left Rib Cage And Feeling On A Pulled Muscle In The Back?
I can understand your problems and will try to help you sort out your problems. First of all we are sad to know that you have been suffering from health issue.
Mam left side rib pain can be due to many causes like yes back muscles spasm or costocondritis or pleuritis or heart related condition. I would like to rule out all by investigation. Chest X-ray and EKG will rule out lung and cardiac condition. If you have local swelling and tenderness it could be local cause only may be costocondritis or back muscle spasm only. But still once I want your pet scan or ultrasound abdomen to rule out splenomegaly. Then I would like to treat you with muscle relaxers like baclofen which can be taken after prescription by any nearest practioner of your locality. Kindly get back to us with above reports for further follow up.
I hope this info helps you sort out your problems and if you feel its helpful kindly give me user thank vote happy health!
