Could a ruptured saline implant be the cause of my pain?

Saline implant ruptures do not typically cause any of these signs or symptoms.  You should be looking elsewhere to determine the cause of your pain.

A ruptured saline implant may cause some discomfort in the breast. Since it was saline filled, you body absorbs the leaking saline. Your list of complaints are not related to saline implants. if the capsule is thick, I would suggest having that removed as well. Please have your medical doctor check you and be evaluated for food allergies.  Good luck to you.

I agree with Dr. Johnson, a ruptured saline implant may give mild pain or discomfort in the affected breast but should not cause the level of inflammation you are describing.   You should see your family doctor for a full checkup first then have the implants removed or replaced.  

A ruptured implant can cause pain, but the discomfort should be limited to the breast, and without infection probably cannot cause swollen lymph nodes. Yes, the implant should be removed, however you should have a full medical work up for your symptoms. It is quite important to see your physician.
