### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
I have a UTI that my doctor confirmed. I came down with a high fever (103.5) on friday. I have a history of UTI s, kidney infections and kidney stones twice. I went to the doctor again no Saturday and they agreed that I probably have a kidney infection as the symptoms at the time were similar to my previous episodes. They did not confirm the kidney infection with bloodwork however. They just figured that I knew well enough. They prescribed cefuroxime for me. Since Saturday I am still running a fever which I have kept down to about 100 - 101 with ibuprophen and tylenol. Now I think that it may be something else. I am not having the lower back pain that I usually have with kidney infections. I am having a lot of abdominal pressure in the front and my back is soar up closer to my shoulder blades. I have never had indegestion but if I had to guess it feels like this. I cannot lie down flat comfortably. Sometimes it feels like when I lay on my right side that my guts are being twisted on the left. I also started my period on Saturday. I also have a massive headache that despite all of the medicine has persisted for 2 days now accompanied by lightheadedness.

### output:

Hello are taking ibuprofen and Tylenol frequently for high grade fever, so these two tablets may be the possibility of pain in the front or abdomen and also intestinal upset (as you mentioned in the query). Fever is high grade, and you are also having intense headache and lightheadedness. Such type of fever may be due to UTI, but you didn't get urine and blood test, so please get in these tests. Also get in serum creatinine and blood urea with ultrasound of both kidneys. Since this time, no doubt symptoms don't simulate like UTI, but you are an old case of kidney infection, so we should not forget this thing. 2 Flu or upper respiratory infection may be the other possibility of such symptoms. So consult another physician and get his opinion (2nd) . Since you are taking cefuroxime and this is not effective because still you are having fever, so 2nd opinion is important.3 Malaria is another reason of such high fever. Get in blood for malarial parasite. However, there are so many other reasons of such fever, like dengue, typhoid but physical examination and 2nd opinion is important. Good luck.
