I've Pulled My Quad For The Last Three Years Doing

I've pulled my quad for the last three years doing pole vault, this year as a senior I think I pulled it again but there is a big lump on my quad, it hurts to even pole vault and sometimes it hurts to walk on, is it just torn or what could it be? Also I took a week off and the lump went down, but I started pole vaulting again and it came back.
