Head ringing and tinnitus


New member
I have taken protein shake for years post workout. I decided to bulk up a little by adding another protein shake right before bedtime. Its just protein isolate mixed with water. Ever since I taken it before bed, I have noticed weird feelings during the morning after waking up, specifically hearing ringing sensation and tinnitus. I made an appointment to do a routine blood work for the next morning, fasted. I eat very healthy and everything checks out good, except for my sugar level being high and unhealthy.

Is it possible for high blood sugar to cause tinnitus, caused by protein shake? What else would cause my ringing sensation? I have stopped my night time shake and the feeling has stopped.

Please advise.
