Your additional info in my spark page comment is very important!
When recovering from injury you normally DO lift much lighter weights and more reps. You should see a qualified physiotherapist and follow their directions.
Normally when I hurt myself it's no weights for a few weeks, then light weights for about 6 weeks (which is waaaay past when it feels okay again), before I'm allowed to challenge that muscle.
Don't risk further injury.
