Is it negligence if I got an electric shock and fell off the exam table due to the shock?

At a chiropractor appointment, I was thrown from an exam table due to receiving an electric shock from electric stem manipulation therapy. Once the electrodes were put on, ice packs were topped, the assistant then pressed down on the neck/electrodes/ice pack with pressure and I received what I feel was a severe electric shock with mild burns like a sunburn to upper back, neck and face. That has partially subsided the next day, although I have been hospitalized due to the event and high blood pressure readings and chest pain. It is now the next day, and I am still hospitalized having cardiac testing done. I asked several times at the doctor if I should be checked, and they blew it off saying I probably had a seizure. I am epileptic. This was no seizure. There was also enough force from the shock, as I mentioned to throw me off the table. I have seen black and white flashes of light during this situation, and feared I was dying. The doctor took my blood pressure at the office, when I asked, he just said it was normal. I asked again what it was, he said normal. I shook uncontrollably for hours later, even after I was taken to the ER by ambulance from my home. I was so unsure of what happened. Regardless of how I felt, I questioned myself if I should be seen so I called a nurse with my insurance company to discuss it, who immediately called 911. The catch here is I wonder about the equipment in the chiropractors office now. A few days before this event, my husband was getting X-rays and the machine blew. My husband thought shots were being fired and he and the doctor ducked. They laughed and the doctor bragged that he should be happy that this machine has lasted 20 years without maintenance. So now I wonder if other machines, like the one that shocked me has gone without maintenance or testing, and is this a claim for negligence? This has totally changed my views on alternative care, sad, because I'm going to school for the field now and I fear if electronic equipment is properly maintained.
