Dear Friend
We need to know your age , sex , occupation and associated medical illness , if any , to perfectly answer your question.
I need to know , whether you have pain in muscles , or pain in joints.
Common causes of Joint pain are :
1. Rheumatoid Arthritis
2. Osteoarthritis
3. Osteoporosis
An other commonly missed entity is
Restless Leg Syndrome , where a patient has continuous urge to move his / her legs , associated with night pains also.
But arms involvement is not described.
Also , get your Thyroid profile ,
Hypothyroidism is also a common cause for bodyaches.
I suggest you to give me complete details so that i can help you.
