I do not think it can be muscle spasm because when I turn my head I can hear a bone click.
I do rub a heat warming cream on it and a warm pad to relieve the pain
You are always welcome to JustAnswer. Wish you a very healthy life.
There can be a few probables. It can occur from an inflammation in the joint, or from a sprain or strain of the ligament. Sometimes pinched nerve can be there. You should get an examination by doctor if the pain continues.. Till then you can apply warm moist compress over it. If the pain is more analgesics with antiinflammatory actions like motrin or advil can be taken if there is no contraindication.Regards.
