Doing an MRI on the wrong side is malpractice per se on someone's part -- whether the prescribing physician's for giving an incorrect order or the MRI facility's because of what may have been operator error. But unless serious consequences resulted from the error, any potential financial recovery would be minor -- it's not as if they removed the wrong arm, leg or eye, and in defense they'd likely try to argue in defense "you knew it was supposed to be done on the right side, why did you let him/her do the left side?" That kind of blame the victim approach is not uncommon.
The pain you are now experiencing after they did the procedure on the correct side is something else. Sometimes prost procedure pain is a natural and almost inevitable result of a procedure or the underlying condition (and if so, they should have told you about that before the procedure), and subsides after a few days. Severe and persistent pain more often is a result of doing the procedure in an improper manner, and results in long term or permanent harm or discomfort. (And I sure would have lost confidence after they did it on the wrong side the first time, so what you're feeling may be the result of malpractice. A few days out it is impossible to tell, but you should ask your doctor.)
If the pain does not subside quickly I would seek the advice of another physician who is independent of the group that did the procedure. And if that physician believes the paid likely means something was done wrong would I speak with a malpractice attorney.
