7 months post op and 18 weeks pregnant, feeling sharp pain - will this stop by my due date so that I can breast feed?

Dear Pinkf555,
I understand your concern. However, it is not possible to tell if your symptoms will disappear on time. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Your breast are likely getting larger with pregnancy. This is certainly stretching the nerves supplying the nipples. Once you have expanded to you maximum size, the pain should subside. There is likely nothing stopping you from breast feeding as the apparatus of the breast tissue, ducts, etc is fully intact with a submuscular augmentation. It could be more sensitive to breast feed with your scenario.

There is no way to accurately predict if the sharp pain you are experiencing will settle by your due date, nor how sensitive breast feeding will be for you. I encourage you to speak to your surgeon who may be able to offer some ways to help desensitize the area somewhat to make you more comfortable.

It is good that your sensation is returning, but how sensitive you will be, no one can say. Your very large implants have stretched your nerves considerably. Hopefully, they will calm down in spite of your hormones and potential increase in your own breast tissue. Most women do not calm down during nursing.
