Problems with my contacts...especially in the winter?

I have been wearing contacts for over 7 years now, and I've never had a problem like this before. I had conjunctivitis in Jan of '10 and ever since then my contacts haven't been the same, on and off. As soon as I put them in, I get excruciating headaches that last even when I take the contacts out. They feel sticky in my eyes and my eyes dry out very quickly. I hate wearing gles and I've seen multiple optometrists and one ophthalmologist, who told me my "eyes might just be changing and it might take 6+ months for them to accept contacts again." Is there nothing I can do? I was fine all through the summer; it seems to reappear in the winter. Any suggestions or comments??
