i woke up the other day with a severe pain in my left foot , it felt like it had been hit with something hard and it was broken as i could not stand on it, shortly after I massaged the area the pain went, it was tender in that spot but nothing else that morning, the following day (today) i have had aches and pains in my legs, sometimes shooting upwards , it feels like i have muscle strain or i have done a workout and my muscles are aching from it (although I have not done any excersize of had any other injury etc)...it is mainly in the back of both my thighs from back of knee upwards but also slightly in calfs i can walk but dont want to walk, even when i lie down the aches are still there...i have very slight shortness of breath which has happened just now, but nothing major, my back is also now aching, hope you can help.
