Each ache help??

I’ve had a ringing/high pitch noise in my left ear for ages now it aches most of the time and it like make this popping sound but I can never get through to my doctors! It all started a few years ago they refused to see me cause of COVID and just gave me ear drops over the phone and ever since I kept getting ear aches but now I’ve had ringing in the ear for a few months and it’s driving me crazy my ear feels full, blocked keeps crackling and it hurts occasionally, I had tried ear drops in the past but that just makes me ear ache worse! What can I do in the meantime to help this problem until I can eventually get to see my doctors? It’s even worse if I accidentally get water in it aswell
