I am female 53 and for the past 3 years have suffered from a swollen and painful right rib cage. I have had an endoscopy, MRI scan and ultrasound for gallbladder all within the last 2 months. The scan showed 2 buldging discs in my upper thorasic spine for which I have had physio. The endoscopy showed up a small hiatus hernia and the ultrasound was clear. My GP also took blood tests for organ function and these are clear.The main problem is that my rib cage is swollen and tender and a muscle/ligament? swells up. The swelling can start at my waist and go up to the top of my ribcage - it can feel like a lump around the bottom rib/kidney area. It was triggered yesterday by sitting in the car (the motion of going round corners). I am restricted to what I can do physically - i.e vacuming, ironing etc as use of my right arm seems to trigger the pain and swelling. My physio said that it cannot be a swollen muscle and it would have healed by now and my GP said that it's not organ related it's muscular. I work as an administrator and have just returned to work after a 3 month absence due to this and I'm not any further on in that time. I would be very grateful for any advice help as I don't know where to go next. I have been at my doctor's surgery many times over this - I feel as if I'm camping out there.
