Donna,
Sorry to hear that you are having such a rough time!
I have just had 3 weeks without lenses because of an allergic reaction too. I think I might have got away with a couple of days however, had I not kept trying to squeeze the hours out of my lenses! I had been used to 8 hours and so I kept them in despite the discomfort (and pain in sunlight.) It sounds like you are being a lot more sensible, so hopefully you will not have so long to wait. I went back to Gartnavel and the optom had a look at my eyes. The cornea was so sensitised by that stage that anything could irritate it, the 3 weeks gave the surface a chance to stabilise and become firm again.
In my case hayfever triggered the initial sensitivity and then I became intollerant to the preservatives in my solutions and my viscotears too. Apparently, when allergies affect the eye, the cornea becomes a bit spongy. The lens can then easily scratch the surface and remove the cells. The lens is then basically sitting on the nerve endings! Then of course the eye becomes sensitive to everything, sunlight, solutions and so on...
The good news is that the cornea cells grow back really quiickly, so even a day off lenses should allow you to wear them again.
I found I was suddenly allergic to things I had not been before:
-Preservatives in solutions
-Hayfever eye drops
-Viscotears
-Systane
After the 3 weeks which just finished I switched to preservative free solutions and I am using the vials of Systane (thanks Gareth

) which are preservative free. The difference is overwhelming!! It doesn't even feel like my lenses are in apart from being able to see
So, all in all I wouldn't be surprised if your reaction to viscotears has lead to other reactions or sensitivities you never had before. Or a seasonal reaction has made you suddenly sensitive to viscotears. I found going in to the clinic was well worth it. The Optom was able to have a good look at the cornea and advise me to give them time to heal. She also had lots of really useful tips on how to manage my allergies.
