I could have written that post yesterday!! I'm so very sorry that you have had such issues. They really s*ck.
I would encourage you to either get on, or maybe increase whatever you are doing/using for inflammation. Mine comes a goes, although many times there seems to be no pattern, no one knows exactly what's going on in my body from minute to minute most of the time. I increased my anti-inflammatories and called it a bad day and stayed off my feet!
And some have not only Bart, but neuro Lyme, they both attack nerves. There is a product that has been shown to repair the myelin sheath, which is the protective covering all of our nerves have. Once that's damaged, messages get mixed up (registering more pain that it should, muscle spasms/twitches/cramps). Here are a couple of articles on it:
