disgusting weight gain

so i find it absolutely disgusting to think that i gained 3.8 pounds in one day--one MEAL. wow! so with some basic rounding it equals 4 pounds which equals 4 miles. i owe you these miles in the near future--the goal was to run them today, but i have a slight injury. the other day (and here is the TMI part) i was on the toilet and noticed a huge green/ black/ blue bruise on my hamstring. since it doesn't hurt that bad i am assuming it is a strain. i should go see a doctor, but i have to pay out of pocket until i reach my deductible, so i will likely skip the visit and rest a few weeks--do some light workouts that don't include much or any running. a lot of stretching and some rehab stuff i learned from my last hamstring injury (same leg--except last time it was a tear). i am hoping it isn't that bad--but time will tell.
