I've been having what I thought were earwax problems: sore ears, feeling of fullness, needing to turn the TV up, occasional ringing and rumbling in my ears. For the past 3-4 weeks I've been putting a drop of olive oil in each ear most nights, and it's really eased a lot. But now I notice that I get intense ringing every time I lie down. Can this be earwax-related, or is it something else? Is this sort of tinnitus something that should be investigated right now? Is there any risk in waiting until the risk from Covid is reduced before investigating?
