Hello,
I have studied your case.
Swelling and warm feeling can be due to synvics shot.
Along with this snap and pops can be due to
meniscus injury.
As per your history there is possibility of
soft tissue injury in knee.
Most commonly meniscus injury occurs.
As per your symptoms you need to do
physiotherapy and knee exercises to improve range of motion .
If pain persist then you may need to do
MRI again to see for any functional defect.
Small meniscus tear can be managed conservatively with physiotherapy with USG and
TENS.
Meniscus injury can be managed by arthroscopic repair.
