That really is terrible that you are having a bad reaction to the medication. To be honest, you probably don't want to be putting anything on it (especially lotion), as it will probably only make it worse.

Obviously I'm going to assume that you have stopped taking the medication and if it is an allergic reaction it will probably go away in no more than a couple of days. Though it does seem strange that it took three days to have a reaction to it.

Keep in mind that it might be something else, especially if you don't have these symptoms anywhere else on your body. You may want to go to the doctor and get this checked out (and maybe you can find out what you are allergic to in that medicine if it is an allergic reaction).

Good luck!
