I Was In The Gym 5 Days Ago, When Seated

I was in the gym 5 days ago, when seated i bent over to lift a weighted bar and as i attempted to lift the bar something in my lower back on my tail bone clicked and it has been sore ever since. ive taken tramadol and other pain killers but nothing has helped. i also came out to work yesterday and due to be away from home for 2-3 weeks.i was wondering if it was suitable to be sent home and examined by a physio?
