Breast Lump and Tightness, Occasional pain, Feels Dense - Any suggestions?

It's important to follow up with your surgeon and continue to monitor the lump and any discomfort or pain you're experiencing in your breast. While the ultrasound may have ruled out any concerning abnormalities, it's still possible that the lump or other symptoms could be related to the implant.

In some cases, breast implants can cause a condition called capsular contracture, where the scar tissue around the implant becomes thickened and can cause discomfort, tightness, and other symptoms. It's possible that this could be contributing to the issues you're experiencing.

It may be a good idea to seek a second opinion from another qualified and reputable surgeon who has experience in breast implant complications. They may recommend additional imaging, such as an MRI, or other tests to further evaluate the issue.

In the meantime, you can also try some at-home remedies to alleviate any discomfort or pain you're experiencing, such as wearing a supportive bra, applying warm compresses, and taking over-the-counter pain relievers as needed.

Best of luck !

At a minimum based on your history of a painful lump in your breast, I would suggest a mammogram and an examination by a breast surgeon other than your plastic surgeon. A breast surgeon may recommend an MRI or may recommend watchful waiting or may recommend a needle biopsy depending on the type of lump or mass seen on an MRI.
In most cases such a lump turns out to be benign. But it is very important that you pursue an accurate diagnosis.
