I have this AS problem along with inflammation in sacroiliac joints as well. From the past few days I have started feeling very tired plus a lot of hairfall has started too and also the back pain has started radiating in my chest, shoulder and ribs affecting my day to day tasks and mobility. I have heard that drinking bone broth can help us overcome all these issues but me being a vegetarian would like someone to tell me how collagen supplements work and which type can be taken by me or if its totally safe in consuming these.
