[|Human|] Ive been on Coumadin for over 2 weeks for stent placement in iliac vein (May-Thurner Syndrome). I have noticed at times a dull pain in back around kidney area. Last night it started becoming sharper. Just wondering if it could be due to the coumadin.
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor, I understand your concerns and I will try to help you as much as I can. It could be due to Coumadin of there was trauma that caused hematoma near kidneys however this i snot common. More likely this may be urinary infection or urinary stones, so you should do urinalysis, monoculture and kidneys ultrasound to rule these out.  In most cases this is self limiting, but sometimes antibiotics are required and more invasive tests. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health. Chat Doctor.
