Having a dexamethasone injection tomorrow...and I woke up with a full ear

It's almost like the universe is taunting me at this point. Fortunately I have someone to drive me to the hospital and bring my home again after. I'm also supposed to be going on holiday on Tuesday morning and I'm so anxious I won't be well. I need some positive vibes :(

I wonder if the injection will calm the fullness? I've never had this type of steroid before.
