Can breast implants cause a pinched nerve after 8 years?

Breast implants cannot pinch any nerve that innervates the arm, with the very rare exception of the injury to the intercostobrachial nerve, which innervates sensation to armpit and inner/upper arm. This nerve is virtually at the armpit level, and when injured (usually during an armlift procedure, not breast augmentation) simply causes numbness to armpit and upper inner arm, not nerve pain. Implants only affect the pectoralis major muscle, and doesn't really 'stretch'; it certainly doesn't pinch nerves to the arm either. What you should do is have your implants and the ENTIRE scar capsule removed and replaced with smooth implants. This will completely eliminate the already small risk of breast implant associated anaplastic large cell lymphoma, but more importantly, reduce any 'velcro effect' from textured implants and the possibility of discomfort associated with that.

Many women notice a kind of pulling discomfort with implants. It may be the implant dragging on scar tissue, but it needs to be examined by your surgeon to make sure there is nothing else going on.

Dear sgray_22,
it is highly unlikely that implants are the cause of your issues. I would suggest you to visit your doctor and get an examination.
