Hi,

So sorry you are having these types of problems. The doctor can be so
frustrating. When they cannot find anything. All the tests. So frustrating.

Sounds like nerve damage. The heaviness, numbness and tingling- strange
sensations are classic signs. I think the intense anxiety before having an
"Attack" is not good. I get this also.

I am also having a lot of muscle pain and symptoms such as you describe,
along with recently having episodes or attacks (whatever you call them)
of not being able to move- paralysis. I am thinking Parkinson's Disease
or Multiple System Atrophy for me because I just watched my dad go through
MSA. Lots and lots of similar things as I am having that have been so
confusing and hard to explain. His disease actually shed a lot of light on what is
and has been happening to me for a long time now.

I am not saying that you have Parkinson's Disease and I hope I don't but this type of illness is similar to what you are describing. Especially in the early
stages. Do you have any kind of sleep problems that you are aware of?
Like, acting out your dreams for instance?

I hope you get feeling better soon and you just have a pinched nerve or something. I don't mean to scare you but this is the insight I have.
