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.
*
Analgesic & anti inflammatory medications
* Local application of pain killer gels
Hope this information is helpful . Good day
