Frozen shoulder typically develops slowly and in stages. Any shoulder movement causes Pain, and range of motion begins becoming limited. Eventually it freezes, your shoulder becomes stiffer, use becomes more difficult, whilst Pain may begin diminishing.
Frozen shoulder manifests as sudden shoulder joint immobility onset, and our intelligent body 'freezes' almost all shoulder movement. As often occurs in other body parts, pathological muscle programming builds Pain over extended periods, though Pain onset may seem sudden.
Releasing tension in early stages with Osteopressure assistance often reveals almost visible 'melting' or frozen shoulder softening. Pain may be noticeably reduced in most cases, though recovery and full mobility can require time.
