I did my second tandem yesterday and had a ton of pressure over my right sinuses... eye, ear and mouth. It really hurt. I didn't have this my first tandem. It took a few hours for my ear to finally pop. I really want to move on to my AFF but I'm thinking that I might need to see a dr first. Besides the sinus issue the jump was awesome. He said I did a great job with my awareness, pull and canopy control. I wonder if he tells everyone that :)
