Yes this is normal. You can ache for no reason at all. Stretching or not. But stretching is good for you. Gentle stretching that is. Don't stretch all the way. Stop when you feel the resistance. Next time go a little farther. You have to get into everything gradually.
They often say that fibromyalgia and Chronic fatigue syndrome are one in the same. You can get chronic fatigue from fibromyalgia. So I think that they really go hand in hand.
I hope that you start feeling better soon. Take care, keep posting.
