Yes, it is generally ok to wear a sling with a frozen shoulder, though it is important to understand the proper use of the sling and the potential risks associated with it. A frozen shoulder, also known as adhesive capsulitis, is a condition in which the shoulder joint becomes stiff and painful, making it difficult to move the shoulder. A sling can provide support to the shoulder by helping to keep it in an optimal position, which can reduce pain and help to improve range of motion.
However, it is important to note that wearing a sling for too long or too often can actually worsen the condition. It is recommended to only wear the sling for short periods of time, as prolonged use can lead to muscle atrophy and further decrease range of motion. Additionally, the sling should not be used to force the shoulder into any particular position, as this can cause further stiffness or injury.
If you are considering wearing a sling for a frozen shoulder, it is best to consult with your doctor or physical therapist first. They can provide advice on how to properly use the sling and determine if it is the right choice for your condition.
