Does this sound like early MS, or something else?

Beginning in Feb 2018:

Electrical “nerve feeling” at a level or two in my mid-thoracic spine. Coupled with quickened heart rate and dizziness. Happens out of nowhere, and not at times where I should feel anxious. Head to the ER a couple of times thinking I’m having a heart attack, only to find out my heart is fine.

March 15, 2018: See a “different” chiro than my normal. Two days later, I begin to get paresthesias (like a brief “wet” feeling, like when it first starts to rain) on my left side. Chest, sternum, arm, back, and leg. Often coupled with the fast heart rate/back throbbing thing.

The paresthesias begin to occasionally go to my right side too. My doctor orders a battery of bloodwork for blood sugar, possible cancer, and HIV, Syphilis, and Hep. All blood work is normal.

In April I begin Physical Therapy for back pain on my GP’s recommendation. I have another ER trip on the 16th, where head down CT scans show nothing major going on besides neck degeneration and two bulging discs in my low back, but nothing exciting going on. In late April my Physical Therapist suspends physical therapy, I think both because she didn’t know if it was helping and she was worried about my heart rate.

After that, the paresthesias spread all over. They don’t last for more than about half a second, but I start noticing them almost everywhere on my body.

A cardiologist says I have supraventricular tachycardia. I wear a holter monitor for a week and they notice several episodes of sinus tach, and one of SVT. I see him again June 1.

On April 25, I see a neurologist who tests my left side/limbs. I have a normal EMG.

My back pain and neck and head pain get worse. I have a back of head headache on my left side for two weeks. I’ve never experienced that before. My left lat spasms for about five days.

On May 15, I finally get head-down MRIs. I have multi-level disc degeneration in my neck, and a 2.7 cm X 3.7 cm arachnoid cyst in the left posterior fossa of my brain. Nothing else major is found. No lesions or tumors or anything.
I have basically stopped all my usual physical activity. Normally I lift 3X a week and play basketball twice a week. I tried lifting very light this past Thursday and was in bad shape half the weekend.
Doctors insist the arachnoid cyst shouldn’t be causing problems. This past Friday my entire back clenched up on the left side, and I was in bed all day Saturday in terrible pain.

On the MS front, the spreading paresthesias have me worried. I still occasionally get them, even behind the eyes, but not as bad as they once were. I haven’t noticed too much in the way of vision being disturbed, but scheduled an eye exam next week. I have also been EXTREMELY tired over the course of this and struggle to get out of bed for work. Now and then my spine feels like it’s “buzzing,” (happened last night) and makes it difficult to sleep. Where the cyst is there is a slight “wet feeling” all day.

I got an online doc to humor me and give me a short course of doxycycline in the event of Lyme disease. She may order those tests this week. My GP referred me for another neuro, but she isn’t available until August. I asked, and my GP says she doesn’t think I have a neurological condition. She has referred me to sports medicine.

I’m still afraid it might be neurological.
