New, waiting for diagnosis

I do have some advice from my own  experience –

First of all, don't bother yourself about which is causing the other because right now you are caught in a cycle that can last for years, what with your weakened immune system making it easy to  elevate your blood pressure which just encourages that infection which again spikes up your  blood pressure which then makes you susceptible to infection  …  on and on -you get the idea

So, once or twice a day – more if you can manage it (I do it morning and bedtime)

Get as comfortable as you can and

try to relax into the tremors and twitches and spend about 3 minutes just allowing your body to feel whatever it feels  - do not ascribe any characteristics to the pain and weakness

(By this I mean try not to think that your body is betraying you, or that your muscles are behaving wrongly because your mind is just trying to alert your body that it  needs a different type of care than 8 hours of  sleep and good hydration )

Then

when you are ready, purposefully reach out to each twitcher, briiefly reminding them what it feels like to be "normal" and function well or at least controlled movement

If you pray, now is the time to do so.

after this try to ease into your daily routine. 

I was surprised to find how much relief it gave me to just allow a space and time for my body just feel what it feels without thinking it is bad or trying to punish me or berating myself for exacerbating the pain through something I did,

I know that this is much more difficult to do than to describe or read so don’t beat yourself up if it takes a while before you can think that your body is causing you pain or is out to get you somehow -

Hope this helps  - good luck
