Hello and thank you for your question,
The results of your MRI mean that you have a lot of arthritis in your shoulder joint as well as inflammation in the tendon of the rotator cuff (tendinopathy) due to it being impinged within the joint.
The treatment usually consists of intense physical therapy to relieve impingement and improve strength and mobility as well as anti-inflammatory medications such as Ibuprofen, which you have already been taking. Occasionally you might need to get a short of cortisone (steroid) into the shoulder to improve inflammation.
Physical therapy usually works wonders for your condition so I would strongly recommend you try to do that first.
I hope you find this information helpful. Please feel free to follow-up with any other questions you might have.
