Good Morning ! It Started 3 Weeks Ago That I

Good morning ! It started 3 weeks ago that I had to spit saliva all the time. I went on holiday and ended up in the hospital because my forehead and eye lids were swolen. After two days swelling come down but I stil have to spit. I went to the pharmacy after my holiday and she gave me a Olbas but it didn't help. What to do? Thank you Esma
