Hi Yota. It can't hurt to continue with any medication or treatment they have given you. Your doctor probably wants to see you again soon to see how you're doing. Am I right? Then it will be a good time to ask about the pains. The tests you mentioned are probably a good idea just to make sure. Anything like this takes some time to figure out. For now try not to worry too much. And maybe not so much coffee if you drink a lot of it.
