FIBROMYALGIA and ED. To turned off?

I was having pain in back so I visited to specialist he told me that I have condition called fibromyalgia but not big issue he gave me medications but because of this disorder many other symptoms occured like i cannot sleep properly feels restlessness & can only get 3 to 4 hours of sleep maximum & whole day I feel dizzy with head ache.I feel sleepy whole day can't Focus on work & also there's some digestion issue everytime when I eat after an hour or little later there's gas issue stomach feels like Flatulence there so many problems with my body and I think these are symptoms of fibromyalgia & is there any possibility of ED from past 3 weeks my penis doesn't erect it get hard in morning only and can't erect even while pissing There are some other things which I didn't know before These symptoms are with me from past 5years.. I get easily angry because of noise and light and very highly sensitive to cold and heat, I cannot tolerate light when I'm at Home I want all lights to turned off
