2 Month Neck Pain

Hi I need solutions!!! I think I injured myself while inverting. When I started inverting 2 months ago I had a problem committing to the invert and allowing my upper body to fall back. I was chicken and would kind of keep looking at my feet rather than let my head and shoulders go down. So what would happen is I would not invert and instead go back to standing position... I think I whip lashed my neck in the process and I'm thinking that's why my neck has been hurting in the neck/ upper shoulder area on my right side.... Any suggestions???
