What Causes Pain In Ring Finger And Bruised Left Foot?

Good evening. Two days ago I woke up with my ring finger swollen where I had to remove my wedding ring. It took two days to go down. This morning I woke up with the balls of my left foot hurting as if I was bruised all the way across. It hurst all day but now seems to have gone away. I also have a sharp pain on and off on the left side of my stomach near by bellybutton. Really hurts if I sneeze or use my stomach muscles. My joints in my left hand and wrist that can go up to my elbow also hurt and throb. Everything is on my left side. I m also having anxiety attacks and stressed. Do you know what these symptoms are caused by? Thank you.
