Hi, wanted to pick some brains! I have had psoriasis for the last 24 years (am 44) which is on my elbows and few bits on my knees but haven't had any treatment for it for years. 18 months ago I went to my GP for some blood tests as I was feeling so tired I was falling asleep the minute I got home from work. The blood tests showed I had vitamin d deficiency. I had a loading dose of supplements for a month to raise my levels. Almost overnight I developed pain in my knees. I went back to my GP for more blood tests, had an x-ray of my knees and hands and then got referred to the rheumatologist. At this point I was getting pain in my knees, toes and fingers mainly.They repeated my bloods, I had an MRI of my lower back, ultrasound of my knees and started physio. I went back for my follow up appointment and was told there was no inflammation and I wasn't "ticking all the boxes" for psoriatic arthritis, was told it was osteoarthritis, to lose weight and take supplements and discharged! I have put on more weight in the last 18 months and am probably 2-3 stone overweight which I know won't help but I find it hard to believe that is causing all of my pain. I wrote a letter to the consultant saying I don't understand how osteoarthritis can come on so quickly and also queried my HLAB27 positive result in my bloods as she had't explained this! The pain has got significantly worse and my GP has doubled my pain relief. I now take Cocodamol daily and Naproxen. I also use my Tens machine daily and heat pads. I'm signed off work as the pain is so bad. I have an appointment to see another rheumatologist privately next week as the NHS rheumatologist can't see me until August. I just wondered if anyone else had been diagnosed with something else before the correct diagnosis? Did your PA come on suddenly or was it progressive?
