I sustained a patella injury while playing soccer 2 months ago and after a month of rehab i was walking around ikea and got lower back pain after a couple hours which was diagnosed as an SI joint injury. I have been in physical therapy and they have me working on my core. However for the past month I have had this uncomfortable sort of squishy feeling under my right rib cage, at the very lowest portion of it (closest to my hips). It's the sort of feeling you get if you bend your body one way and the feeling of the compressed muscles on the other side. My PT said it could be my oblique that is tight by stretching hasn't done anything for it. Any ideas?

Not entirely sure what your "uncomfortable sort of squishy feeling" is under your rib cage. Since you have initiated a new PT/core strengthening program, you may simply being compressing and straining structures you have not used or felt with your previous activities. From your description, you may be feeling your "floating ribs" or 11th and 12th ribs. These do not attach on the front of your chest at the sternum or by costal cartilage to the ribs above. This can sometimes give a feel of firm but compressible structures on your side between more securely anchored ribs and your hip.
Other extremely rare structures in that area could be an extra rib (intrathoracic supernumerary rib), and enlarged liver, abdominal masses or something as simple as stool in your colon (full of poop). If you are concerned, I would always defer to your primary care physician for a more appropriate physical exam and review of your medical history.
I've had this feeling for the past month, it all started when I had the initial back injury. It's definitely muscle related and I feel the sensation mostly when i'm sitting at work for a period of time.
