I called my doctor about the pain
after 4 days of it not going away, and they told me to take vitamin E
and see what that did, and to lay off the caffeine. (Besides tea, I didn't drink a lot of caffeine, anyway.)
A week after the pain started, I began checking for lumps to find a possible cause. I did find a lump.... to me it felt small, round, and hard, and in the top right, deep down. I called my doctor again, and they scheduled me for an examination.
