Its a hot day (85), and Ii was frustrated in getting the mower started.(so BP was up) About 45 minutes into mowing, my left ear drum seemed to just have a load roar, and my hearing was like I had just jumped into a swimming pool - sounds seemed louder-(like someone just bumped the volume up on the radio) I finished the lawn, went to basmenrt to lay down in cooler spot. Now I have a mild feeling of pressure on my head behind my left ear. I am 64, healthy, no meds, but this was first time cutting the grass on a hot day this year. Are my conditions symptoms cause for alarm?
