Hi, It's Aliza (the BC patient and Med Librarian). We've chatted before, so two things: You should call your doc (plastic surgeon) re your pain because it sounds a little lengthy for it to hurt this long and advise her/him of that and see what she/he advises.
Second, remember, everyone's different. We all have different pain levels (I have a very low pain tolerance-I'm terrible!!) and different areas of sensitivity and this might be one of yours (since you haven't been operated on here before [I'm guessing]). It sucks! The drains made me uncomfortable and unhappy too, but not for as long as you.
I hope you feel better soon!! The one piece of advice I might be able to offer you is to try and distract yoursellf (difficult as that is) as much as possible. Crossword puzzles, scrabble and gin rummy (if you have a partner, Netflix, a good book (hey, I'm a Librarian, what did you expect?...;) There's a neat online kind of book group called wwwdotgoodreadsdotcom where you can track books you've read, make virtual friends, join small genre book groups, write book reviews, and read others' book reviews. It can be a lot of fun, especially if you invite your friends!
I know the drains are a pain, try to remember that all of this is a temporary pain (like an awful root canal [I know it's a lot worse]), but see what the doc says and see if she/he has any suggestions re mild heat (or ice) to help? Don't do anything on your own!!!
Keep us posted!!
