I'm pretty sure I'm suffering through a pretty serious case of Sciatica right now. My lower back has bothered me for a couple weeks but as I've tried to increase my amount of running the past few days it's spread pretty painfully down the back of my right leg. My back actually feels better while I'm running but the sciatic nerve behind my right knee has hurt very badly during my last two runs and then my back has been very sore after these runs. Last night I don't think I slept more than an hour consecutive because I just could not get my back to relax the whole night.
I was supposed to go back to work tomorrow but I had to call my boss and delay this because I just don't think my back could take the stress of standing for 5 or 6 hours consecutively right now. It feels good while I run but I've noticed that standing in one place is almost impossible.
My plan for now is to not run through any more pain as I have the past two days. I'm taking today off completely and then if I feel better tomorrow I will try an easy run, but this time if the back of my leg starts to hurt I will not push it any further (On Sunday I did 17 miles and it started to hurt a bit at mile 5). And if the running is restricted for several more days then I'm just going to have to try some biking and weight lifting in hopes that I can at least do a little something to keep some of the fitness that I was just starting to build back up.
At this point though, the hardest thing is my mind, not my body. If I can't work and I can't run I have way too much free time in my head. I've been trying to read more and I have a long list of "chores" I need to get done sometime, but my training is always my catalyst for these other things. When my training is going well I find myself much more ambitious throughout the rest of the day, but when I can't train at the level that I want to be training at I find myself often unable to motivate to do the other things I should/could be doing.
