When I bend over, I have pain in my ear. Is that normal?

Ear pain when bends. It is not normal to have ear pain when you bend over. There may middle ear or eustachian tube dysfunction. Please visit your primary provider or otolaryngologist for evaluation.
No. Your description sounds like an inner ear problem...Equilibrium also if you possibly get dizzy. This doesn't necessarily sound like a TMJ problem (my field.) i would get to your doctor and then he/she will need to probably refer you to an ENT specialist.
