Angelia --
Thoughts are with you. I periodically get ear pain, which I find is usually due to spasm of some of the small muscles adjacent to the sternocleidomastoid muscle. This can be a side effect of the radiation fibrosis that sets in. Can't tell if you had neck dissection, but that also makes the whole thing worse.
Keep us posted, but with BOT and the treatment that is used for that, neck issues are common.
