So I woke up with this today and it still hasn't stopped. I'm getting really worried now. I haven't has a cold or anything. I did have a practical yesterday where we were dealing with e coli and t4 phages but I didn't even touch my ear??? Help!
could be earwax, maybe a hot(ish) bath and letting your ear fill with water for a few minutes will fix it... if not there's over the counter earwax remedies in pharmacists shops.
