Hi. I've been treated for suspected psoriatic arthritis for about 18 months, but I have no psoriasis. Now I think AS is a possibility and wanted to know what other people think.
I've been getting lower back and hip pain on and off for a couple of years now. For the last few months it's been getting worse and waking me up in the very early morning, I can't turn over and am very stiff. As soon as I get up, it eases off and I maybe get a little pain during the day if sitting for a while. I often get pain in the buttocks on the same side, knee, and sometimes the pain goes down the back of my thigh on the same side. Hip x-ray was normal. I've also been getting bad achilles and right shoulder pain.
There's a tender spot in my right SI region and my lower back and hip often crack and pop when I get up from sitting.
I have had pain and swelling in a few fingers, pain in my feet and ankles, heel pain (right at the back so it's uncomfortable to walk shoeless), and also get a stiff and crunchy/popping neck sometimes. Blood tests are normal. I've been taking sulfasalazine for a few months and the finger/hand pain has improved but this does not seem to help my back, hip, or achilles pain (which is just getting increasingly worse).
I'm having an MRI of my pelvis soon. I don't tend to have pain once I'm up and moving around, and sometimes have good days when the pain goes away completely. So, if the morning pain is caused by sacroliliitis/AS, will the MRI show anything if I'm having a good day? And how likely is it to pick something up if it's in its early stages?
I had a bone scan a couple of years ago which didn't pick anything up in my back, just inflammation in my ankles and feet. But I've had pain in the lower back/hips waking me up for about 18 years - it used to be only when I slept in a different bed from my own. No matter how comfortable, I would wake in the early morning in agony. It was only in the last few years when I started to get other joint problems and my back/hip started getting worse that I even considered this could signify a problem. I always assumed I was just fussy about my mattress.
I'm a woman in my late 30s. I haven't had an HLA B27 test. Any thoughts would be appreciated.
