How Long Do Muscle Spasms After a Breast Augmentation Last?

 

         It’s not unusual for
patients to have muscle spasm following breast augmentation, especially when
large implants are placed beneath the pectoralis muscles. In most cases, spasm
has resolved in three to four weeks following surgery. In the short term muscle
relaxants, stretching and massage can provide relief and shorten the duration
of muscle spasm.

The muscle spasms usually break in the first two weeks or so.  After that, it is typical for the spasms to be intermittent for a month.

It is quite common to have muscle spasms after having breast augmentation under the muscle. The pectoralis muscle is cut along the breast fold and a breast implant is then placed under the muscle. The muscle is therefore stretched, contracts and has spasms for several weeks after breast augmentation. Stretching exercises where you would lift your arms over your head help to reduce spasms. Massaging the muscle also helps. Some surgeons prescribe muscle relaxers or Valium to help with muscle pain. It is normal to have spasms for 3-4 weeks after breast augmentation. 

Those are some big implants. You could expect some muscle spasms. They will get better in time. Probably several months. Best of luck.

Thanks for the fantastic question -
Muscle spasm after sub-pectoral breast augmentation can be caused by the stretch of the pect. muscle when the implant is placed beneath it. However blood and manipulation can also cause muscle spasm. The larger the implant the more likely the spasm.
Typically the spasm resolves after about 1 - 2 weeks as the muscle irritation decreases.
In our San Francisco area practice we have worked extensively on a regimen that reduces spasm which includes medications for the first few days as well as specific exercises for patients more prone to spasm.
I hope this helps.
