Not an Achilles tendon tear, but pretty bad!
Last night I pulled a muscle in my calf, simply by playing with a stupid cat that keeps coming in my yard. I was squirting it with water, because it keeps messing with the birds/squirrels in my yard, so as I chased it with the hose off towards the back yard it stopped and looked back at me, so I decided I would take off running towards it and as I leaped forward into a run (not even close to a full sprint) I felt something pop and then within a few steps the pain hit me like a ton of bricks.
I couldn't even limp back to my front door, more of a hop with all weight off my now injured leg. I couldn't put any weight on it and could only slightly angle my foot before the pain hit. Today the pain is better, but I don't think I can even go to a store, it would be too painful and I don't even believe I could drive too well; I know I couldn't drive last night, the pain was just tremendous.
First thought is that I did a sprint without warming up, but I've done this before, so I'm thinking it's a combination between not warming up, but mostly from the very tough calf workout I did the other day.
This SUCKS!!
