I am age 70 have had fibromyalgia 20 years last 12 months having multiple new symptoms following covid. Extreme periods of fatigue, crunchy leather feeing in bottom of feet, colon shut down for months at a time, had am mri of brain shows right trigeminal neuralgia and punctuate t2 hyperintensities with demylinazation and gliosis. Put on cybalta and tegratol. This helped my depression. Still feel weak and fatigued. Any help?
