Reactive arthritis | Arthritis Information

I was diagnosed with reactive arthritis 2 months ago after a bowel infection (food poisoning during chrstmas holiday in egypt) I thought ReA was supposed to clear up between 3 and 12 months, by the looks of things it doesn't.
Inflammation first started in my heel then big toes, both knees, slightly in fingers and now top of neck, giving me awful head pain and numb arm wen wake up.
Iv'e had 3 steriod injections which give you false hope as the pain goes only to coe back in about 3 days.
I take 3 diclofenac a day
1 tablet to minimise bleeding due to diclofenac
4 Sulfasalazine (started 1 a day increased to 4 over a month) only been on sulf a 5 weeks, no side effects but no ease of pain yet.
I take upto 8 tramadol a day for pain, these stop the pain but are very strong they make me really dizzy and I find it hard to sleep.
Is there anyone out here whos symptoms of ReA have gone, need lots of hope.
I have been sick from work for almost 3 months, I'm a 32 year old teacher and find it impossible to teach at moment with pain or feeling I get from painkillers. I was a fitness fanatic too, went to the gym 5 times a week loved it, I haven't been able to go for 3 months, really frustrating, I really want to hear from someone with hope please.

I am HLAB27 positive and my c protein levels are between 150 and 190
