Over the last few months I have been flying constantly due to the career path I choose. I have been to several military doctors but they seem to not know what s wrong. I constantly have ear crackling in my ears and jaw. I sometimes have a tingly feeling I my throat . When I stand up for too long I tend to get pretty dizzy and have to sit down. I Also been having problems when it comes to eating every time I eat something I feel the need to have to clear my ears. I feel my ear drums move but I still have this real fullness feeling n my head. I also seem to have problems with bright lights since all these problems started I have been really sensitive to light in my eyes. and finally when I fly I can sometimes feel like a sharp pintching feeling in my face or around my ears and makes my ears swore. If anyone can help that would be awesome thank you Michael
