I had a breast lift with silicone implants 9 days post op... i am having a lot of pain in between my breast..is this normal?

Improving or not?: The most important question is if the pain is getting better slowly, or not. If you find that it is not, then evaluation is needed, as occasionally problems can happen this late. Evaluate your pain medication use after surgery, which should be less than over the previous week by now. If you still require as much or more, then further evaluation is needed. In any case you need to follow up asap.

Common: This is technically not normal, but it is very common.

Increasing pain?: If the pain is bothering you enough to ask here, you should call your plastic surgeon. In general pain should get a little better each day. Most the time it is the result from the injury that surgery causes. Sometimes pain is the sign of a problem (bleeding, infection...). The best way to check, is to be seen by your surgeon. Good luck. :).

Could be normal: Pain after any surgery is normal, but you shouldn't just assume yours is normal. See your surgeon to make sure everything looks okay, that there is no infection causing pain, or bleeding, etc.
