I went on a scuba diving trip (while in great health) about 6 weeks ago. I felt fine after the dive but about a week later I started to get "brain fog" for about an hour per day for the next week.

I then took two flights on consecutive days and my problems progressed to blocked nose, ears, sinus headaches, and also brain fog. I was given antibiotics and decongestants. These helped but not completely. I went back to the Dr. and was given a steroid nasal spray. This also helped, but I am still sufferring from blocked ears. The blockage starts to disappear a bit after taking decongestants (nasal and sudafed) but it comes right back after they wear off. I am also having trouble sleeping. I'm not sure if this is caused by anxiety, medication, or my symptoms.

I'm a 24/M who has always been healthy. Sometimes, I have allergies and a stuffy nose, but I have never felt this bad for more than a few days.

I plan on going to an ENT in a few days but am looking for support in the meantime. Does anybody have any other ideas to unblock ears or what I am sufferring from? I am worried about overusing the decongestants. I am starting to get frustrated. Thanks for your help!
