Hello Imtan,
Welcome to the Pain Management Forum. I am glad that you found us but very sorry to hear about your pain.
Fibromyalgia often presents with the type of symptoms you are experiencing. I am far from and expert and there are not physicians on this forum....but generalized pain and aching is often a Fibro.
You are always welcome here but you may want to post your question in our Fibromyalgia Forum. Here's the link:

There are other conditions, such as Chronic Fatigue Syndrome that may be responsible for your pain and fatigue. See a physician that specializes in these areas. Sometimes a rheumatologist can be beneficial or point you to some one that can help you.
I wish you the very best and hope that you will let us know how you are doing.
Take Care,
~Tuck
