weak in my left arm???

[mr.elite]

i was busy planning for leaving to training. so i did not work out for about a week. i went to the gym and i streched and was about to do a light bench for a warm up. when i lift, my left are was very weak. it didnt hurt. my right arm was normal. my dominant hand is left. so usually my left arm is stronger. anyway. its been about 4 days now and i went to the gym and its still the same i did bicep curls and my left arm was very weak then my right. what do you think it is. by the way i took some advil right now.

Eat right, hydrate and just work through it.
One arm is always weaker than the other. There are times I can only do 6 curls with my right arm than on my left I'll do 10 or 12, other times I'll be able to max out at the same number.
Not sure why it happens but it's nothing serious and it's completely normal. Don't fret, go lift.
