Agree this is not true as chemicalpop said. You can get a CT quicker (which can also rule out/diagnose certain head injuries and conditions). If you need a CT and PCP is not helping, you can either find an urgent care near you- call ahead and ask if they do MR OR CT scans on site and if they do either ask how much it is. Worst case scenario, go to Abington hospital on York road in willow grove. You will wait about 7+ hours but they will do a CT and review. If nothing is wrong you’ll go home, if you need to be admitted, they may do additional testing at that time. Lowest cost option is definitely an urgent care.
