If u are considering surgery, shoulder, heres u r item, the icesleeve, and the owner of the company is very very accommodating and will do what he can if the product doesnt fit correctly. Theres an ice machine out there, this is how I stumbled on the ice sleeve, no machine needed, get the ice sleeve its great and fits very comfortably. U can use it on any part of u r body! I took NO narcotics. The ice sleeve and I were best friends! GREAT PRODUCT!
