Using an ergonomic chair and making sure that your workstation setup is comfortable will be very helpful to get rid of rhomboid muscle pain.
Depending on the cause of your muscle spasm, a chiropractor may help with stiffness in your thoracic spine. Still, just getting rid of the stiffness won’t solve the underlying causes like muscle weakness that caused the pain between your shoulder blades.
A postural brace will make you more aware of your posture and force you to sit upright. This may sound like a good idea, but the muscles that should be holding you up will just keep on getting weaker as the brace takes over their responsibilities.
Using a sling might help to relieve your shoulder blade muscle pain, but only because you won’t really be using your arm. A sling puts your arm in a dysfunctional position and your upper back muscles in a stretched position. Of course, this stretched position is often what caused your muscle spasm in the first place.
Your GP can prescribe muscle relaxants and other medication for your painful upper back. On the one hand the medication will help with pain relief, but on the other hand it won’t solve the actual problem. Almost like hanging a picture over a crack in the wall. The crack will still be there even though you can’t see it.
After completing treatment with your physiotherapist, you will have relief from your shoulder blade pain, but might not be strong enough to be completely rid of the problem. Our muscles take time to adapt, so getting stronger is a longer process, especially if multiple areas are causing your pain. This is where a biokineticist comes in. They can help you with a supervised exercise program and keep on adapting your exercises as the muscles around your upper back and shoulder get stronger.
