Hi, I have pain in my hamstrings but also on front of thigh.very painful going up stairs or even talking only one step.I feel shaky when I stand up or get out of bed. Now I know I have torn something in my right shoulder which is also but strangely my left shoulder is now causing lots of pain. I get the worst pain across my collier bone and my neck gets stiff and painful. I am in pain all the time and very tired. All this has got much worse in the last week.
