If it was just problems equalizing, I would agree with Walter and say just take it slow, and also, the more dive, the easier it will get.
However, since you also say you have sinus problems the next day, you really need to see an ENT. Just try to find one who is familiar with diving...best if he/she is a diver as well. I have a lot of sinus problems and used to have trouble clearing. The first ENT I went to had never dove, and knew nothing about it. He said you won't/can't don't even try it. The second was such a hard core diver, he took orders to Guam (second time there) as a Navy Captain to fill a much more junior job just so he could dive. He checked me out, said you are going to have some problems, just take it slow and understand you may have to abort now and then if you can't clear.
