WARNING... frozen water bottles may do more damage than good

I keep a water bottle in the freezer and use it to roll the bottom of my foot on for my plantar fasciitis. It has provided amazing relief until two nights ago...  After grocery shopping and adding more stuff into the freezer, the bottle was perched precariously on the edge of the shelf. And then when I opened the freezer to get out the ice cream... I learned a painful lesson. WARNING!!! Frozen water bottles may do more damage than good!  As I opened the freezer door, the bottle fell out of the freezer and landed hard on my left bare toes. I screamed bad words, then cried, and proclaimed that I had a broken toe or three... Someone suggested that I ice them immediately, but the thought of putting the offending item on my swelling toes was not appealing. It hurt so bad that I couldn't walk. By the next morning, I was able to limp around. 24 hours later I attempted an easy run; it hurt, but wasn't unbearable. So I had high hopes that I'd still be able to complete my long run today. But it just didn't happen. I quit at 8 miles in a lot of pain. I hope it's not broken...  Can you guess which one?
