I have about two UTI's per year. With the last one, a round red hot rash appeared on my lower left calf. Now, I have another UTI and I awoke this morning with another round hot red rash in the same area. How can a rash on my leg be connected to a UTI and should I be conerned?
Hi and welcome to the forum! I am glad that I can help you.
You want to know the cause of the symptoms that you experience.
Certain individuals are more reactive to different substances and are prone to allergies. All medications including antibiotics may cause allergies. The allergy is characterized by a rash or urtica.
According to the data that you described, it is likely that the rash is due to an allergy to the combination of trimetoprim and sulfomethoxazole. You may consider stopping the treatment with this medication and avoid any additional usage of the same. Have a bacterial culture with an antibiogram taken from a urine sample. You may also need to take antibiotics according to the antibiogram results, but avoid the combination of trimetoprim and sulfometoxazole.
