hi,
thank-you for providing the brief history of you.
A thorough neuromuscular assessment is advised.
As you have pain and tingling from the knee to the foot, it could be related to a
nerve pinch in the spine.
As the
tingling sensation is a commest feature of the nerve impingement. Also, for swelling of your knee, you need to apply icing to reduce the swelling.
Understanding that the knee joint has a bunch of ligaments and any pathology of it may lead to swollen knees. Undergoing a thorough musculoskeletal assessment and an MRI scan will assist in understanding the soft tissues.
If the clinical assessment comes closer to the
neuropathic pain more, than an MRI of the
lumbar spine will be advised to see the nerve impingement. Usually by clinical assessment it can be confirmed and an MRI of lumbar spine may not be advised.
Undergoing
physical therapy like - Therapeutic
ultrasound therapy and
TENS therapy the pain and swelling will be reduced. Post which exercises will be taught to strengthen the muscles and in about 2-3 weeks of time you will be fine.
Also , to understand that you can perform this exercises at home taught to you by a physical therapist as it will maintain the long term care of the symptoms.
In my clinical practice I advice patients to undergo physical therapy and 99% recovery is achieved.
