I fractured my tibia just below the knee on July 8th 2015. My doctor had me start physical therapy and adding weight to it on August 28th 2015. Since I started putting weight to it I have been having a lot of pain in my knee along with swelling and a lump that popped up on the lower inside of my knee. My doctor wasn't concerned with this and is having me continue putting weight on it. I recently had a MRI and it showed a possible horizontal tear of the medial meniscus should I continue putting weight on it or go for a second opinion?
