Hello - I used a neilmed and none of the solution drained out and i can feel it in my head. I now have a horrible headache and both ears hurt and can feel the solution in my head - as if I got water in my ears from a swimming pool. Is there any way to get all the fluid out? if so do you have a video of how to show exacly how to do it? Thanks Dr.
