Reactive arthritis survivors/sufferers

Is there anyone that I can speqk to about Reactive arthritis as I genuinely dont know if its this or another type or arthritis.

It all started from food poisoning (camplyobactor) 6.5 months ago

I first started getting symptoms around the 4.5 month mark which started with burning zaps around my body, discomfort/aches around my knees and elbows

As i’m at the 6.5 month mark, about 11 days ago one morning I woke up and my physical spine, tailbone, neck was in deep pain. Since then its calmed down, still a few aches and pains which is on/off.

I’ve got another blood test in 2 weeks time and have a MRI booked in the next up and coming weeks. I’m really scared that this is AS

I havent had any swelling in my joints, no swelling or abnormal lumps,
