My (r) knee is hurting. when i lay down if i bend it. sharp pains go down my leg. i don't remember hurting it. i take asthma meds. what can i do. ?

See ortho: This has nothing to do with your asthma medication. Have you fallen back and braced yourself with your arms lately? If so, this could be from a Baker's cyst. On the other hand, knee pain can be caused by many other things including other forms of injuries. If the problem persists for more than a few days or worsens , you need to see an ortho. Has NSAID helped?
