I thought I posted to this -but don't see it. If this ends up showing up twice, my apologies.
Yes, I do get this and I thought it was just me - I get paranoid thinking everything I feel is related to Lyme - who knows? But I've had "ear issues" as you describe. I feel like they're tender inside and also "full". They also hurt at times to touch them - like if I put a finger in them or pull on them gently- they hurt. I've had my reg dr look into my ears when I feel the discomfort and the "fullness' - she only sees "redness but no infection, swelling or fluid."
What helps me if I can do it (impossible to do at work, for example) is to apply warm, soft heat -like with a covered heating pad or a sock with warm (dry ) rice, etc.
I hope this helps and that you get some relief soon.
