It is me again! Having a difficult time in dealing with the healing process but also the ongoing daily pain. The two do not seem to belong together but they are! Anyway, my question is: I am having headaches & is that in connection with the nerves growing that causes off & on headaches? Plus my skull bone behind my left ear is very tender & feels swollen? Would it be OK to put some pain lotion [Aspercreme] on that area?
