Post COVID neurological pain that I call "spiciness"

Hi all. Im a 31 year old female with no medical issues and play rugby professionally. I got COVID in June 2022. Took me 2 weeks to 'recover' but had months of brain fog, extreme fatigue, heart issues (palpitations and even a trip to A&E for heart attack related symptoms). I have had hyperbaric chamber therapy for a couple of months and used a micro current device. My brain fog and fatigue cleared up with treatment but this neurological pain or 'spiciness' as I call it always comes on after anything remotely active. It's in my ENT and around my head, and normally requires a decent chunk of sleep. I also get it after massage.

My question is... does anyone else have this pain and triggering after using/getting blood flow to muscles. And how can I treat it? Does it indicate I've done to much or will I always react like this? It makes me scared to try anything 🙁
