My wife is a CCM and she does suffer badly with hayfever, which often leads to her not being able to clear her ears on landing. Very painful and she goes deaf from time to time as a result.
I'll give you the same advice as I gave her.....go to the doctor, explain the situation and do as he/she recommends.
My wife (for the first time ever!
) took the advice and the doc prescribed some pills which have releaved the situation.
Go see the doc....get yourself well....fly safe.
