I just got over a cold a little over a week ago. I started jogging again in 50 degree weather. I noticed very minor discomfort in my left ear, but only once in a while over the last 3 days. As i was waking up yesterday I was dizzy, the room was spinning. I sat up in bed and dizziness went away after a few seconds. I also had minor discomfort in my left ear. It feels kind of full. About 2 hours later, I bent down to put the cat down and the room started spinning again. I feel to the floor and once again the dizziness passed after a few seconds. I went to the doctor and he said my ear canal was inflamed but not infected. Also that this was related to my cold. He recommended Mucinex D which i have been taking for 24 hrs. I still get dizzy from time to time mostly when lying down or if i turn my head fast. I'm don't really have any sinus congestion or cough. Blood pressure was perfect at doctors and no fever. i'm 5-9 200 pounds and when not sick jog 5 to 7 miles a day. I rarely drink alcohol.
