Just after some advice really. I've got psoriatic arthritis, similar to rheumatoid and I'm doing really well at the minute. On anti tnf injections which has helped loads and I feel 'normal'. However I still have a few issues with my lower back, not horrendous but it still aches. Anyway, whenever me and dh have sex I'm always in pain the next morning. It actually wakes me up and is really sore. Does anyone else get this? I'm going to mention it at the hospital in a few weeks but it seems to be getting worse. No pain during sex it's just the next day.
