Good Afternoon Doctor; I Suffer From Allergies From Trees Etc.

Good afternoon doctor;
I suffer from allergies from trees etc. not from food ??? and as a result my lips are swallowed 3 times the normal size, are burning and cheapen , they itched and are red all around.
I was prescribed to take Reactine 10Mg once every 2 day by an allergist and tried at first 10Mg per day up to 20mg per day with no result. My family doctor has prescribed me some cortisone 1% which I have stopped since no change was apparent.
I tried Vitamine E with no result and now using LaRoche-Posay's Cicaplast and Nutritic again with no result.
My allergist is not available and I cannot stay like this ...
Can you help?
Thank you.
