That sounds very unpleasant. I am sorry you had to endure that. Spasms are so incredibly painful and scary. It’s a long list of tools in my toolbox, but without a diagnosis you won’t have access to a lot of my tools. In the interim, most SPS patients find heat to help. Heating pads, hot tubs, saunas, hot baths, infrared sauna bags to use in home, etc. Also Tylenol and THC (if you are open to that) if you have not been prescribed Valium yet. Low stress, quiet, and lower lighting help. Sometimes light stretching. Heated massage guns, if tolerable. Massage therapy, light or deep depending on what your body can handle.

Try to keep a journal of symptoms and take videos and pictures as things happen.

I hope this helps and the new doctor can get you a proper diagnosis.
