Hi, thanks for writing to HCM.
From the given description of symptoms, I suspect some soft tissue injury
inside the knee joint. You could have injured -meniscus
or capsule of knee joint or ligaments of the knee.
Inorder to diagnose an intra articular problem, MRI
scan is mandatory as it picks up the lesions with great accuracy.
Temporarily follow the below mentioned guidelines to get pain relief -
* Rest to the injured part and don't involve in activities which puts additional strain on the injured tissues.
* Ice packing should be applied for about 20 minutes once in every 2 hours.
& anti inflammatory medications
* Local application of pain killer gels
Hope this information is helpful . Good day
