<bot>: Hi, dairy have gone through your question. I can understand your concern. You may have some meniscus or ligament injury.  Wait for the x-ray results.  If it is normal then go for MRI knee.  It will give you exact idea about soft tissue injury.  Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
