Right side part of head. On this!

Hi I wear lenses and I put kajal yesterday . My right eye had some reaction and it started getting reaction on my back head portion above the neck and back shoulder rib portion also started paining . I had one side shoulder pain problem and it got cleared by exercise and therapy . In the night I woke up suddenly and sat in one place my heart beats started raising feeling very heaviness in whole body and was not able to sleep . I didn't had any medicine to take but felt some itichiness in throat so took gelusil and tried to sleep  today morning I got up and I still feel the itichiness in right eye and little  pain in back shoulder I am not sure why does this happen only on right side eye and the sensation I feel at back head lower  portion Pls suggest a solution on this
