Now I am sporting this look:
So yeah, it turns out it wasn't tendonitis. I actually do have a fracture in my foot. Awesome. I have been walking around on it for the past three week making it worse and popping ibuprofen like tic tacs. Ibuprofen is a great anti-inflammatory, but it also impedes bone growth.
The doctor was looking at my foot and pressing on the tendons on either side of where it hurt and remarked that it would be very unusual to have tendonitis in only one tendon. She also bent the middle toe back and forth and said since that wasn't causing any discomfort that it was very unlikely that it was a tendon issue.
She left to go look at the x-rays they took and when she came back in she said "Yeah, you have a fracture." I had the disk with the previous x-rays and she took them and looked at them. She said she could possibly see it in one of them, but she also knew where to look since she'd already looked at the new ones. I know stress fractures can be hard to see on x-rays so I'm thinking I've made it a lot worse these last few weeks to make it show up.
I go back on August 22nd for the follow-up. She said it could be 4 to 6 weeks to heal, but if it feels better before that (no more swelling and no more pain) then I don't have to wear the boot the whole time. She did caution that people who aren't as aggressive with wearing the boot will take longer to heal. So I guess that means I will be wearing this bad boy for our vacation next week. Excellent.
On the bright side, I am happy to have a definitive diagnoses and to be on the right path to getting this all fixed. I just can't believe I won't be able to run for probably another whole month. Ugh.
