I have been an AS sufferer for many years,keeping backpain to a minimum by making sure I am always on the go.Iritis, however seems at times a bigger problem,flaring up approx. twice yearly for last 10 years.Being new to the forum,I don't quite know what to expect,but anyway maybe there is someone out there now who does actually understand our problems (I do find that most people haven't a clue what we have!!!)I have read through quite a few postings here and realize I am no different to other sufferers.The biggest worry is that symptoms eg leg pain,ankle pain,fatigue could be put down to AS but may be something entirely unconnected?? However,I try to keep a good sense of humour. I now come to my question, I am 5'8" tall and only wegh in at approx. 10st.--Does anyone have an idea of how I can put some weight on easily and at least look a bit healthier--or is this weight issue all part of having AS?? I look forward to your ideas.
