Do not know if it is a spasm. Whatever will make it feel better![]()
I have a recurrent spasm in my neck so I can empathise with your discomfort. Ibuprofen during the day & ibuprofen and a glass of wine at night (the combo relaxes the neck/shoulder just that much quicker). It wont release the spams though, just give you some interim relief. Physio or acupuncture is still one of the only ways I have found that can release the spasm; even then it takes a few sessions.
Good luck!
