Contacts burn my eyesss?

Okay so this whole problem started at around January. Idk how it happened but as soon as I noticed, my contacts are literally burning my eyes causing them to be bloodshot and I cannot have them in more than 10 minutes. No matter what I do; (I have monthly disposable) get a new pair, wash them with the solution a 1000 times. And about 2 months ago I went to the doctor and they gave me a new brand of contacts but they still burn. All of the other solution burns my eyes even more. I wore them a year ago and this never happened, plus I take allergy pills every day.
