Could I have been exposed to Hogweed years ago? I have problems with light in the mornings and I cover my windows and skip school?

the plants were 50 big thick stemmed plants growing in my backyard and I played in them when I was younger…I tried cutting it with a knife and I tried to tackle them and I couldn’t damage any of them… what kind of plants are these and could it describe what happened to me… I was photo-sensitive for years after. I Looked on Wikipediea and the plants look similar… but with-out the flowers on top
