Since starting up my running again last week after being sick, I've noticed some unusual muscle soreness. I wasn't sure if it was because I was rusty from taking a week off or maybe it was from my medication. A recent thread on the ultra list discussed how certain antibiotics can cause excessive muscle soreness and also weaken tendons. Yup, after some further research, it turns out the medication I've been on, Avelox, is in that category. I really think it's more the medication than rust. In the future, I'll talk to my doctor about other medications that may do the same job and are sans this anti-running side effect.
Saturday's trail run in particular felt like it beat me up more than it should have (more so afterwards), so I rested yesterday. Tried the elliptical machines at the school today, and perhaps it's somewhat psychosomatic, but the muscles felt too tight and I decided to call it quits after 13 minutes.
All in all, not a big deal. I'm just about done with taking the prescription and suspect things will return to normal shortly afterwards. I'm still planning to run a 50K Fat Ass down in Cape Cod this weekend, but I realize I may have to cancel if I can't rebound in time.
Since I already used a picture of the world's smallest violin after whining a few weeks ago about being sick, I'll just post this video instead:
