What I discovered was that my constipation (due to over use of antacids) was creating pressure on my bladder that caused the same symptoms.
This is what helped: lots of fluids including unsweetened cranberry juice, water, a splash of ACV in filtered drinking water, and non-caffeinated herbal tea (especially dandelion root tea). I added 500mg of magnesium once a day (near bedtime) to aid with the constipation. I added extra fiber to my diet including fresh kiwi, whole bran cereal, and flax and chia seed and honey in plain Greek yogurt. Also, a warm water bottle placed on my lower abdomen really helped calm the spasms.
It will take about 5-7 days, but it does work. Always find out if you have a UTI first before treating.
