Leg Cramp #1

I have been worrying about this for a long time. The leg cramp almost happened a few times, but I managed to flex my muscles to stop them. 

Yesterday was a long day. Finished work at 7pm. After having dinner with ah Lun, I continued working at home until 11:30pm. 

Not sure if this was a long day causing me leg cramp. But it was really bad, the sad thing was Ah Lun was not around incidentally in the bedroom. Ouch...... This was so painful.
