I keep having bladder spasams and I know I don’t have a UTI because I just finished Macrobid. Is there something I can take or an herbal remedy for bladder spasams? It feels like I have to go minutes after I go but no burning when I pee.

I have been taking macrobid for a few days now,but nothing seems to be relieving it.Drinking water,cranberry juice and green tea,but still my urine is a dark color….anyone else know of any other home remedy for bladder infection?
