Hello!
You should consider RICE, pain medications, activity modification by limiting movements and weight bearing and by following proper ergonomics in your daily living.
You need to wear a knee brace and if required your orthopedician will consider a below knee cast to help your menisci recovery.
Take care!
I assume your meniscacal tear has been verified with an MRI and phys exam. The menisci does not heal itself. It is like a tear in a piece of paper and it continues to tear without intervention. An orthopedic sx preforms a knee arthroscopy and debrides or cuts out the tear/smoothing the area. Popping,clicking and pain are symptoms of a tear. OTC anti inflamatories and elevating the knee reduces the swelling and pain.but will not heal the condition. If tear/damage is severe enough arthritis develops as menisci acts like a cushion between the knee joint. Louise
An orthopedic surgeon would have advised you of this and discussed options. If you have not seen a specialist, do so.
