Seeking people who may have experienced side effects after taking Nitrofurantoin (Macrobid). As soon as I started taking it August 2018, within 24 hours I was experiencing sharp electrical impulse pain to the medial malleolus of the left ankle. There were times when I would jump from the joint I would suddenly get. A year and half later I still have these electrical impulse shooting pains but now in both ankles. I was on the medication for 1.5 doses. PA misdiagnosed the pain as cellulitis and gave me a second dose which after 2 days I stopped. Pain is worse at night; usually wakes me during the night.
