about 5 days ago I had a painless spasm, quite a large spasm in my left rib cage area along my side. Since then they haven't stopped. It's been about 75 percent of the day I'm awake, and I assume when I'm asleep because I wake up with it. It feels like a heart beat on my side, but I can feel it under my hand when I place my hand on my side during the spasm. It ranges from mid rib cage to high up under my arm and even in my arm. Also stretches around to the front of my chest and to my back, but mostly under my left rib cage along the side. The spasms are painless but since they have started I am having extreme pain and weakness all the time, possibly from soreness from the spasms, but it hurts all along my chest and both arms. I have a history of diagnosed anxiety that I have thought of more as an undiagnosed heart problem, my family has severe heart disorders. I hesitate to go into the hospital as I have the experience of any issue I have being ridden of as anxiety, but it's not the case at all. This is a very severe level of constant spasms. I feel it more at rest than when active. As soon as I sit or lie down the spasms start up, or at least I can feel them more then. On a side note I have had breast implants for about 12 years and don't know if that could be anything. I also have had weight gain, 60 lbs, over the past year and a half due to taking antidepressents for the diagnosed anxiety. Any help or advice would be appreciated.
