OOPS REHABILITATION
SHOULDER - GENTLE

REST & MASSAGE

REST

Ly on opposite shoulder and rest arm on a pillow.
Ly on back and place arm on a pillow which supports up to the shoulder.
Use a pillow support when in sitting. 
SLING

In standing, wear a sling until it is at least moderately comfortable without. After 2 days, leave the collar off until pain begins to return or increases. Each further day leave the collar off for longer periods providing pain is not severe, until you no longer need it. If you cannot follow this guidance due to ongoing pain, see a doctor. 
TAPE

Go to the taping page and follow the instructions for the shoulder. 
STROKING MASSAGE
