Hello doctor! Dear doctor, I am 4 months pregnant and have had tinnitus in my left ear for almost 3 months. I keep having tinnitus when sleeping or just sitting and it doesn't go away, the ringing in my ear is very loud. Doctor, can you tell me the cause and treatment for tinnitus when I am 4 months pregnant? I have had insomnia for a long time and I am afraid it will affect the baby! I really hope the doctor can advise me, thank you!
