Ear and head related. After a month)

Symptoms- Ear ringing (mostly in the left ear but rare in the right side), pain deep inside the left ear, felt dizzy and lost of balance sometimes, pain in certain parts of the head (pain at certain points of the head, not like a normal headache though). This has been happening since 18 months. Recently before 2 days, I was casually sitting outside after lunch, all of a sudden I had a tendency to fall towards my right side for like 2 hours, where I didn't feel any tiredness or fatigue. (like when we were spinning in circles and later we would likely to fall on one side). The ringing and pain in the ear continues and it has been worsening every day (with slight changes, mostly noticeable after a month)
