Hiya,
My dad had Psoriasis, and has recently been diagnosed with Psoriatic Arthritis. However after unbearable pain, that moves to different places, primarily knees and lower back, has had a blood test that has confirmed that he is HLA-B27 Positive. As this was not explained at the doctors, and the internet had little information, i'm looking for info about what this means, the complications and also the possibility that this could have been passed down to myself?
Many Thanks
