Hello.
Thank you for your query at DoctorSpring.com
I have read all details.
You are already a patient of fibromyalgia and arthritis with that you are passing nights without sleep ,all this is imbalancing biochemical equation in body. Since you already have both these conditions, a sleepless night without matress aggravated your condition and hence the excruciating pain.
In this situation I feel that you should first have a good sleep.You may take help of your doctor and may have a prescription of a sedative medicine.This will help in reducing your pain and agony.
Hope this will help you,
Regards.
