Is it alright to use heat around my knee, but not on my knee to treat patellar tendinitis? - tendonitis causes more condition_treatment

I have patellar tendinitis in both knees and I RICE Ing past three weeks, every 4-6 hours and taking an NSAID and rest, so I'm wondering if it is a good idea and recommended that the heat on my knee, the quads and hamstrings on to stimulate the circulation. I know I have heat in my knee, which will only cause more pain than is good for warming up the quadriceps and hamstrings
