This is what pain specialists are for. See if you can get access to one. (Sometimes there is no functional damage but there is neural damage that won't show on structural scans like MRI. Managing it is what pain doctors are for. An orthoped won't know how to do that just like he can't treat asthma.)

You also want to get an immunologist, by the way. You appear allergic to way too many things, and it's indeed possible that either you're allergic to something in the preparate (there are preservatives in drugs, too) or there is an underlying condition.
