I would recommend that you tell the doctor things exactly how they happened. It's important for the doctor to know what medications you have taken and in what doses. It will help in better treatment of your condition.
Fibromyalgia is a condition that causes chronic pain and fatigue. It is generally associated with extreme sleep difficulty. The management of pain in fibromyalgia is very difficult as there is no particular organic cause of pain. It needs a combination of opioids and behavioral techniques.
I would recommend the following=
1)Consult psychiatrists who might be able to help you in decrease the symptoms of fatigue and pain. There are various behavioral techniques that decrease the sensitivity of brain to the pain.
2)You can consult a therapist whom might assist you in various relaxation techniques such as muscle relaxation and meditation
3)Decrease the intake of caffeine, alcohol and nicotine as they sensitize the body to pain and increases insomnia.
4)Try to cultivate hobbies to take the mind off stress and fatigue. Gardening, cooking, painting has been shown to decrease symptoms of fibromyalgia.
5)I would also recommend you to follow a strict regimen of diet and exercise so that you can condition your body to prevent episodes of fatigue and pain.
