There are three distinct stages to this self limiting condition. A freezing stage were your shoulder movement gets more and more restricted and very painful. This can last up to 9 months. This is worst part of the process, as it can be refractory to even allopathic medication. The frozen stage is when the shoulder joint is literally completely restricted mobility wise, no way you can comb your hair or reach with your affected shoulder for that cup of tea. This phase again can last in the region of 9 months. And finally, for no apparent reasons the shoulder joint regains its almost full mobility (90 or 95%) after another 9 month period.
