ER thinks ligament injury, DR is doing what insurance wants, so no MRI.. my foot has been swollen 7 days?

So last week early in the morning I twisted my ankle, it made a pop and I fell down the stairs. ER thinks I damaged my ligament, maybe a tear.. they did an xray.. nothing broken. . Im wearing an ace bandage, an air cast and im using crutches.. I followed up with my doctor on Monday who proceded to poke my swollen ankle till I cried.. needless to say, its been 7 days since I fell.. my ankle if anything is swelling more and sometimes hurting more.. is this normal for my ankle to still be swollen after a week? It looks like a golfball took up residence on my ankle
