I had saline breast implants eight years ago and have never had any problem with them.Suddenly ,about 3 weeks ago I have begun to have some pain in my left breast only.It is not a relly bad pain and is very sporadic some days not at all and just feels like a kind of electric shock pain ,usually only few seconds at a time.Occasionally it will kind of ache for a few hrs. on and off. I cannot recall any inqury except that I did try out a new exercise machine and did some extensive pulling and stretching.I have been contributing it to that but it has been 3 weeks and just a little concerned.
