I had a frozen shoulder, over a year ago it took a good year to heal, messed up my whole life, fitness, sleep, i'm still recovering physically trying to catch back up with the fitness i lost, i'm very glad it disappeared; a doctor said it was arthritis, i was like... ***??? it wasn't, it disappeared by itself after much rest, life change and stress management, but i am very cautious now. Sometimes i feel a twinge during exercise and just hope it never returns. I was on heavy prescription pain killers that were addictive, codeine 30mg/500mg at one point i was on about 12 a day, the pain was so bad. i had a deep tissue massage by someone that made it even worse. Eventually it will go; time, patience, rest, good diet, lower bgz and being kind to yourself is a good healer. Through it i learnt that my body was telling me something so I had to sit up and listen. I hope it gets better for you soon.
