About a week ago I was struck in my neck by linetwist right after opening. After that my neck was gripped by crossed risers and head press down (chin to chest). That happened very fast and was very painful. I could not release the pressure on my neck but managed to untwist the lines and land my canopy. After that I could not sleep for 2 nights because of constant pain in my neck and still can’t turn my head. I hope that my spine is not damaged. I would like to know how to protect myself from this type of event in a future.
