painful?!

How possible is it that the only symptom of thrush is pain? I usually don't get pain till after the itch occurs, no itch yet but pain. 
I had painful sex last night w and oke up with a little discomfort - only enough to notice it, same thing has happened tonight. It was as if I was too tight and now I'm in pain again 30 min afterwards. 
Yes we lubed up lots, my partner and I have been together almost 6 months and this has only happened once before and I treated it as thrush then it went away.
