I flew from Texas to Georgia a little over a month ago. After the flight my ears continued to pop for about a week. Also when I talked it would feel wierd,the best that I could probably explain it is, it was as though I was talking with a box over my head. A few days after the pops stopped I started to get a tingling in my right ear. It felt and still feels as though there is a small insect crawling around in there. Now, as of last week, I've started getting neck pains on my left rear side between my shoulder and scalp. I just got my hair cut yesterday and the pain became unbareable, but as soon as I left the barbershop the pain went away. I use Q-tips so i thought the tingling must be from backed up ear wax so I've been flushing my ear but the tingling is still there and now my right ear will,on rare ocassions, make a rumbling sound. The kind you get when you have a hard yawn. Any ideas on what could be causing this?
