Looking for Answers if Possible?

Hi All.
Hoping someone can help me get answers.
Here is my journey. I am 68 and have always been in excellent health. July 2021 I woke up with pin and needles in my hands and feet, and didn’t think too much of it. When that lasted for days I was beginning to get concerned. From there it went to brain fog, weakness in my arms, a weird swallowing sensation, and the worst was muscle twitches all over my body but particularly in my arms and legs.
Over the next few months, I had extensive blood test done thinking it might be Lymes disease which I did have 35 years ago. Bloodwork continued to come back negative no matter which test they performed. I then had an MRI with contrast of my head and neck, that came back with normal results. I had an EMG with normal results . I then had a skin biopsy which did come back with peripheral neuropathy. My score was 2.1 and 2.3 respectively in foot and calf. I continued with tests, had a lumbar puncture, spinal fluid came back with normal results. Here we are in November 2022, although the muscle twitching is not as bad as it was in the beginning, and I do not have arm weakness or swallowing issues at this writing, what I do have is
Occasional blurry vision
Normal and very low blood pressure depending on time of day
A feeling of breathing irregularities like after you have been crying hard
Minor muscle twitches
A feeling of electricity running through my body
Sometimes when I am still in bed I feel little explosive bursts in my head when lying down
And the most recent (past 2 months) every joint in my body makes a cracking noise upon using that part of my body, ie, knees , feet, neck, arm, jaw, fingers, etc.
Going for another EMG tomorrow to see if there is a change from a year ago.
This is exasperating as no one can help me get to what is causing all of this.
Any input would help tremendously.
I would like to have hope.
As a side note, I take no medications, some supplements, all blood work is normal.
