i got a knee injury last week while playing soccer. i leg was tackled hard from the side and i heard 'pop' sound. so i suspect it was acl or any other ligament injury. my knee is swollen now. currently waiting for my insurance to approve my mri scan so i just need ask anyone who has experienced before or anyone with medical background to help me for the moment. 1. is surgery necessary? 2. if i dont go for surgery or going for it a few months later cos i'm gonna be busy with work and my wedding in 4 months , how long should i rest before i can do light exercise 3. i played tennis occasionally with friends, would tennis have any bad impact on my knee? 4. any tips to reduce pains and swelling. would RICE help?
