I am sorry to hear about the symptoms that you are getting. if you haven't already made an appointment with your GP then it maybe a good idea to do so.
It is really only a GP who can assess your symptoms and give an opinion on what may be causing them. It maybe because of your posture and sometimes some gentle exercises or some physio may help. The GP can assess the type of pain for example whether it looks like you have pulled a muscle.
It is always a good idea to get any persistent symptoms assessed so anything serious can be ruled out.
The Patient Association has some tips on how to get the most from your GP appointment which you can see here
