6 months post op and nipples are still numb - when should I expect to regain feeling?

It's not uncommon to experience changes in nipple sensitivity after breast augmentation, and it can take time for sensations to return. Here are some key points to consider regarding your situation:
Healing Timeline: After breast surgery, it can take several months for sensitivity to return. Some patients may notice improvements in sensation within a few weeks, while for others, it may take up to a year or more.
Nerve Recovery: Nerve endings can be temporarily disrupted during surgery, leading to decreased sensitivity. As healing progresses, the nerves may regenerate, and sensation can gradually improve.
Individual Variation: Everyone’s body responds differently to surgery. Factors such as the surgical technique used, the type of implants, and individual healing processes can all influence the timeline for regaining sensitivity.
Consult Your Surgeon: If you have concerns about the lack of sensitivity in your nipples, it's important to discuss this with your surgeon. They can evaluate your healing progress and provide insight on what to expect moving forward.
Patience is Key: While it's understandable to feel anxious about this issue, many patients find that sensation gradually returns over time. Staying positive and giving your body the time it needs to heal is essential.
If you have further concerns or if the lack of sensitivity continues beyond a reasonable timeframe, your surgeon may have additional recommendations or treatments to discuss.

Change in sensation is one of the risks from breast augmentation. Typically it resolves within the first year after surgery as swelling resolves and tissues heal. Changes that remain after twelve months can be permanent. It is a good sign that you've had some improvement in sensation.
