Yeah well my GP just shoved this aside and I didn't do any reasearch about it, because I try to avoid reading about symptoms etc. in order not to get 'biased', like interpeting too much or influencing my diagnosis (does this make sense?) but as you were asking about it it came back to my mind. Maybe I should check in with a specialist as I just now tried to find some information and it seems to fit really good, it even matches some minor other problems I had earlier (and my GP himself diagnosed me with)
Thank you for your answer, I appreciate everyone wo is taking the time and effort. Well, my brother has spondylitis ankylosans. I asked my doc about it (my mother always warned us to have in our mind when something comes up) but he said that this is not related and my symptoms wouldn't match as I am too young. He also stated that it especially has nothing to do with low back pain. Other than that, no chemicals, no radiation (we live in a area where this actually can be a problem so it is quite common to check for it and we never had any elevated levels) I'm not working in a high stress environment, no heavy lifting or something like that and I move quit regularly during the day
