Brief Answer:
Consult your doctor and consider switching antibiotic

Detailed Answer:
Hi and welcome. This is probably allergic reaction to nitrofurantoin which is not uncommon. You should consult your doctor about stopping taking it and switching to another antibiotic such as ciprofloxacin or tetracycline which can also be used for uroinfection. If you started to take some other antibiotics then these could also be potential alergenes.
Wish you good health. Regards
