Compression Bandage Repetitive Stress Knee Injury - Ice, Compression & Elevation?

Repetitive Stress Knee Injury - Ice, Compression & Elevation? - compression bandage

Working in a cliff, took me in some of the stubborn rock with my right foot. I was wearing heavy boots and adjust kick with his finger on the rocks. If I noticed any pain during the day. The next day my right leg was a little stiff, barely perceptible. Now 3 days later, my right knee was visibly swollen and stiff - even without pain. I'm on my way to the pharmacy for Advil, Ace bandage (compression) and a few bags of frozen peas. Is this the right thing to do? Other ideas?
