Hi i have been having spasms under my chin, in my chest area and if I move or stretch in a awkward position I will get a serve muscle spasm. My doctor doesn't seem to know what it could be. I have had breast cancer and radiation, and chemo. I first noticed the muscle spasms was during chemo. My doctor adjusted the medications and it didn't help. I also have issues with my hand cramping up like I have MS or arthritis and at times my right had( the side of the cancer) the flat part of my hand (below my pinky finger) will seem as if the blood drains out and then a few moments later fill up again. I know this may be alot but I need so answers, I have been having pains behind my ear and at my temples...please help
