Dear Maria,you have not mentioned your age.Any way the good thing that you have done is gone for e.c.g..The other reason could be some nerve compression or muscular stretching due to some bad working habits or sleeping pattern.Please avoid lifting weight for some time.Use soft pillow.Apply some local analgesic cream and please see an orthopedic surgeon if pain persists.Excessive thoughts can not lead to pain.

Dear Maria,good hear from you again.As you are having pain in multiple sites there could be some nutritional deficiency like calcium and Vitamin B12.Please look for it.As fas as your diet is concerned you should be taking good amount of milk products,more of fruits and vegetables so that you can build up muscle mass and remain healthy.Also go for some exercise which helps to maintain your muscles in good shape and you will build up muscle strength also.Avoid taking too much of cold drinks and junk food which can aggravate the problem.bye and take care.Please take adequate sleep and avoid stress and anxiety to avoid things like blood pressure at early age.The children will also listen to you if you speak in hard and mild tone even without shouting.
