I went to the doctor yesterday afternoon to have my back checked.
The diagnosis: muscle spasm.
What do I feel whenever I have muscle spasm/sprain? Stiff! When the pain's at it's peak I can't move my arm. A simple act of reaching for something is very painful already.
Yeah... I know I know... Well, I knew that carrying heavy things can trigger the sprain I had before, and I did too much weight-lifting last week.
At least doing yoga will be good for me. I hope my back would get better soon!
