Hey Ouch
Heather Lynn hit it on the head. High blood pressure is totally linked with sleep disorders. I strongly suggest a sleep study. I was just dxed with sleep apnea and severe plmd, which made fatigue and pain much worse. I started on a CPAP machine last week and my BP went down 30 pts.A sleep study would help at least rule out another cause.
You also mentioned that any exercise made your muscles feel worse, that weakness is associated with the myalgias, including polymyossitis, which can be treated with corticosteroids (not my fave, but I'd take em if they helped.
I hope you have a lower pain day and keep posting. We are all rooting for you. Take care
