What Can Be Done For Vision Disturbance After Fall?

I had a fall and landed under my husbands semi. Hurt my back and smacked the back of my head. At first the redness to my right eye didn t even cross my mind. My back was in so much pain! But by the next day I couldn t see clearly. My eye was red, bloodshot. I thought for sure I had conjuctiveitice. Come Monday I saw my Dr who said it wasn t and most likely I had dirt in my eye from my fall. I made an appointment and saw my eye Dr. He assured mr there was nothing in my eye and I had no infection. HELP!!!! What should I do? Two weeks now and my eye can go almost back to normal and then in no time BAM RED as if someone poked me with a hot stick! I was asked today if I had coolant in my eye? Cold that be it? Help! Please!
