What is the cause for flank pain after a hx of kidney stones when on ASA?
Patient: I have a hx of kidney stones, was having flank pain yesterday. went to the ED, they did a CT scan, was negative for kidney stone. I continued to have pain, all through the night. It has went from my left flank area to my left chest area. I also have a gastric band. I don t want to go back to the ED if nothing is wrong. But I also don t want to wait until something goes wrong. I know its sharp pains, worse when I breath. I took 324mg of ASA this morning, been extremely fatigue and sleepy but serious pain. What could it be? I have read various scenarios. I am a RN, don t want to over think the situation but I also don t want to injure myself by not seeking help.
