Greetings, sorry about the pain and failed treatment by physio. Your suffering from muscle stiffness at various joints including head, you are moving towards a condition called fibromyalgia. No to think it as something a bigger issues. It is due to unbalanced lifestyle (dehydration, lack of proper sleep and poor diet plus no proper exercise regime,etc)
