Suggest Cure For Pain And Soreness In Knee

I'm 24. I had twisted my knee while playing badminton. For the last 2 and a half months, I had been suffering from slight pain on the knee while complete bending and also while standing up after a long seat. Doc suggested for an MRI, MRI reads -'ILL defined hyperintense signals are noted to the posterior body of the medial meniscus- Grade-1 injury. Anterior cruciate ligament demonstrates normal Tibial/Femoral bony attachments. Its midsubstance/Femoral end appear bulky and of increased signals-Interstitial injury. Posterior Cruciate ligament per-se appears normal. Very minimal effusion is noted into the joint capsule. Everything else reports normal'. Doc has put me under physiotherapy. Physio gives me some exercises and provides some other treatments like Ultrasound therapy, Infrared therapy and ice packs for 15days. Moreover I have to sit in the office for long hrs. Now, my question is that Will I be able to run without any pain after the therapy? Is the recovery going to take more than a month from now? moreover, due to meniscal injury(possibly) I feel pain under the bottom circumference of the patella. Is there any medicine for this apart from pain killers?
