The night after my x coun run, I felt pain from my lower back. I can barely bend down on 7/2/2016. It's really painful once I move my lower back.
This isn't the first time.I guess sometimes I have a bad posture when I am sitting or standing. There maybe linkage between my calf strain and plantar ficistis and lower back pain. I didn't do much, simply getting some rest by not having any training.
