I’ve had another thought, many of us have a low temperature (for instance 35.4 – 35.7 is normal for me). Do you know your base temperature ? When a GP looks for signs of infection, they will look for a raised temperature. Now a raised temperature, for many of us, would be 36.5 – which is everybody else’s normal temperature!! Therefore infections can be missed when based on temperature. I always remind my GP that I’m normally low.
I am wondering if you have an infection and need anti-biotics. It maybe where you had your ear surgery. This would cause inflammation and raise your intracranial pressure, particularly on the left (which would explain the accentuated right sided symptoms). You may say that your surgery was months and months ago but, let me tell you that we don’t heal like most folk. I’ve had infection occur within a scar that’s been there for many years.
Just wondered if it may be worth asking your GP to take your temperature in both your right and left ear (just in case there is a difference between the two).
