Why Does My Wrist Hurts?

Hi! I have had a couple of bad teeth for about 8 or 9 months now. I feel horrible every morning and I struggle during the day to make it. Then by the time I get home to 3 children I am exhausted. I am dizzy feeling a lot of the times and i don't know I just don't feel well at all. About 2 months ago one of my wrists started hurting me and it still does like maybe I have sprung it or something but it doesn't go away. Help I need to feel better.
