It may or may not be 6mp. Deep vein thrombosis (DVT) and venous thromboembolism can be a risk of having ulcerative colitis. I don't want to worry you but perhaps it' something to check out as soon as possible. With me all my problems always seem to happen on a weekend but you've got tomorrow Friday to call and ask your GI.
Here's a link:
www.ncbi.nlm.nih.gov/pmc/articles/PMC2689424/and a quote from that link
The key to reduction of risk for thrombotic events in inflammatory bowel disease patients appears to be the control of the inflammatory process per se. Also, some of the medications used to treat ulcerative colitis and Crohn’s disease may directly inhibit platelet activation. These include 5-aminosalicylic acid (5-ASA)-containing medications (eg., mesalazine, olsalazine)[22], azathioprine and its metabolite, 6-mercaptopurine (6MP)[23] and infliximab[24].Hope you get some answers. Good luck.
PS Are you the pill? The paper (link) said oral contraceptives could also be a problem.
