Thank you for posting your query.
First of all, I would like to reassure you that your MRI images of brain are normal and there is no disease as per those images (however, I should point out that all images were not present here, as full MRI would have about 100 images). Also, if you have a radiologist report on MRI, you can send it.
I also agree that your symptoms are suggestive of fibromyalgia with chronic fatigue.
Medications helpful would include pregabalin or gabapentin. In addition, please look for vitamin deficiencies such as vitamin D and vitamin B12.
I hope it helps. Please get back if there are any more queries.
