hi,
thank-you for providing the brief history of you.
As you mentioned you have pain and swelling of the knee. Also, the painful area is behind the knee joint, it appears to me as the
ligament injury. Also, if you have an
arthritis it may lead to such pain and symptoms of swelling.
I advice you to do the
MRI of the knee and expose the internal structures of the knee joint. Which will help us look more deep into the knee joint.
Also, taking a
physical therapy like - Therapeutic
ultrasound therapy and
TENS therapy will help you with relief of pain.
If there is ligament injury confirmed on the MRI then avoiding the knee bending for time being will be of choice. As to avoid further damage.
Also, to understand that if you have any vascular symptoms then a Doppler will help look deep into the matter and the medical management will be guided accordingly.
Performing exercises at the later stages of life is of due importance to understand the needs of the muscle Strengthening and functioning of the knee joint muscles.
Usually patients recover with 99% , as I have seen seen with proper conservative management.
with the grace of God I wish you a speedy recovery
Regards
Jay Indravadan Patel
