Yes, could be a UTI. But whatever it is it is a question for your doc. Don't waste time with us, because you need to be checked out on this one. From the number of times we get this question you are not alone. See the doc, and wish you good luck.
Seriously? People have to stop following google to AgingCare to ask about this issue, it should take less time than it took to sign up to read through the dozens of more relevant web sites, and besides that we are a caregiver forum and we are not going to have an answer for you. If you suspect a UTI see your doctor. If you don't know, see you doctor.
But, the doctor is the only person who can answer your question. Try not to worry at this point in time and make an appointment with your doctor.
Best wishes to you.
