Hi yes some people like this should get an MRI in case it is an aneurysm.
Perhaps the sooner it is done the less likely there will be of loss of limb or life.
Oh yes while waiting for the doctor's appointment day to come I would not bend over like that and try to avoid things which cause intraabdominal pressure such as lifting, straining at the toilet, sneezing or coughing.
I would skip the advil since it can cause major stomach problems and even perforation.
