Thanks for contacting HCM I am sorry to hear that you have recently been diagnosed with a tear to the left Meniscus. A meniscus tear is a physical rip in the cartilage of the knee and your bodies full weight is turning on that cartilage. these type of tears do not heal spontaneously. You can reduce the pain by using anti-inflammatories and doing low impact exercise. Wearing of a knee brace may also help stabilize the knee, reduce pain and further injury to the meniscus. Hope this answers your question. Please contact us again with any of your questions.
