Very strange physical symptoms

Hey, just wondering if anyone has gone through something similar because I'm starting to get desperate.

I've had pretty extreme anxiety for 18 months every single day, every single moment. All started after seveare throat pain (never found anything. I've had these symptoms ever since:

-muscle twitching all over -tingling in hands and feet (especially when touching warm or cold things) -skin sensations like crawling and tingling -random patches of skin that tingle for weeks -jaw tension -throat tension -tmj -eye pain -insomnia -jerking limbs -stomach pain -buzzing limbs -elbow pain after waking up -hypnic jerking when falling to sleep -Head ache

These symptoms are constant but wax and wane in strength. Im exhausted but look healthy. I'm extremely stressed at all times because of these symptoms.

I've tried SSRI but didn't work. I've tried going to the doctors but they say anxiety (completely get that) but no one can explain these symptoms.

I've tried to calm down but these keep in a horrendous state. Has anyone recovered from this before?
