Suggest Remedy For Persistent Inflammation And Pain In Knee

Question: I am a 53 year old nurse who is having problems with my right knee. It has been off and on issues for years which have lead to a nasty fall and epistaxis. The knee feels like it catches and causes severe pain to bear any weight. I never know when it will occur and it is occurring more frequently for longer periods of time. I am unable to bear weight due to the pain when it occurs. It always feels tight like there is swelling in the knee joint but does not look swelling. I had a recent MRI results read s follows
EXAM: MRI EXAMINATION OF THE RIGHT KNEE
CLINICAL INFORMATION: Right knee pain and swelling. Catching and locking. Chronic, recurrent and worsening symptoms.
TECHNICAL INFORMATION: Multiple proton density images were obtained in the axial, sagittal and coronal planes, followed by proton density fat suppression images in the axial and sagittal planes. Coronal T2 fat suppression images were also obtained. There are no prior studies available for comparison.
INTERPRETATION:
Bones: Localized mild subchondral cystic change at the patella. There is no evidence of acute fracture. No other abnormal bone marrow edema pattern is identified.
Ligaments and tendons: The medial collateral ligament is intact, without acute sprain or tear. The iliotibial band, fibular collateral ligament, biceps femoris tendon and popliteus tendon all are intact. The anterior cruciate ligament is intact without acute sprain or tear. The posterior cruciate ligament is intact.
Extensor Mechanism: The patellar and quadriceps tendons are intact. The medial and lateral retinacula are intact.
Knee Joint: There is a small knee joint effusion. No discrete popliteal cyst. Synovitis, without a focal loose body.

I have a long standing history of AS and am on biologics and cannot take antiinflammatories anymore I recked my stomachs from years of use. I am unable to do steroid injections due to being hospitalized twice with angina from my microvascular heart disease after a clerical injection and a foot injection. I was told to go to PT but if I can't bear weight what are they going to do. I had recent tarsal tunnel surgery and gastric muscle release on the right foot and calf in January of this year. Should I get a second opinion?
