The symptoms you describe, burning during urination, discomfort for a few days, and dark yellow urine should not be attributed to "body heat" alone. While dehydration can make urine darker and occasionally cause mild discomfort, severe burning during urination warrants evaluation to rule out a urinary tract infection (UTI) or other urinary conditions. Since you have had a UTI in the past, this could also represent a recurrent UTI.
I would not advise taking Urifast or any previously prescribed medication without a medical evaluation, as the cause of your symptoms may be different this time. Self-medication can delay the correct diagnosis and may not be effective if the bacteria are resistant to the earlier treatment.
Next Steps
Consult Doctor at the earliest. Get a urine routine examination and culture before starting antibiotics. If a UTI is suspected, especially if this is a recurrent episodeâa urine culture and sensitivity may also be advised before starting antibiotics. Drink adequate water to stay well hydrated. Avoid delaying medical consultation by relying only on home remedies such as curd or other "cooling" foods. While these may be part of a healthy diet, they do not treat a UTI.
Health Tips
Seek immediate medical attention if you develop fever, chills, vomiting, pain in the back/flank, blood in the urine or if the burning becomes progressively worse.
