The best treatment for a frozen shoulder is do not lift anything heavy at all, as this will make it worse. Keep away from washing baskets; lifting babies /toddlers, carrying heavy bags of shopping and doing heavy housework. I had a double-banger of frozen shoulder. I got it in the left shoulder, and in a matter of weeks it was on the right side at the same time. I couldn't lift my arms up over my head, so dressing and undressing became very difficult, as did sleeping. Reaching up to get something off the top shelf was also very painful.
