<s>[INST] I had a CTSCAN of my stomach and pelvic area about 4 weeks ago - the day after the scan I went into what felt like hyperthyrodism (spelling) , BP up, vomiting, sweating, day or 2 later i noticed my tongue swollen, then my face is swollen and other areas i just discovered not to easy to see *wink are swollen.  I tried antihistamines but they are not working.  Should I see about a GP about predisone.  I drank the oral solution gastrografin - which i have found similar side effects as I am mentioning as well as a delayed reaction to the solution. [/INST] what about your urine output, is it normal or decrease because dye can cause kidney problem leading all manifestation. So should get renal function test done. you should see gp. he ll probably prescribes you some drugs which will increase urine output </s>
