I'll try anything at this point. What are your warning symptoms of an outbreak?

This is interesting since cow's milk is acidic to the body. I wonder if you are drinking almond milk?

I just came across this site/post, and while I know it is more than two years later, I am sure it goes without saying to do your own research before following a suggestion.

I have suffered from CIU for more than 20 years, and after a terrible flare, have been willing to try "almost" anything...

Per https://www.healthline.com/health/ph-of-milk:

Cow’s milk:
Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.

Other dairy products like butter, hard cheeses, cottage cheese, and ice cream are also acid-forming. Yogurt and buttermilk are alkaline-forming foods despite having low pH levels between 4.4 and 4.8.

Goat’s milk
Like cow’s milk, the pH of goat milk depends on how it’s treated. Raw goat milk is alkaline-forming in the body. However, most goat milk available in stores is pasteurized and acidic-forming.

Soy milk
Soy milk is made from soy beans, which are legumes. While most legumes are acid-forming foods, soy beans are neutral or alkaline. Usually, soy milk is alkaline forming in the body.

Almond milk
The American College of Healthcare Science’s food chart notes that almonds are an alkaline-forming food. Almond milk is also alkaline-forming. This beverage has many other benefits as well.

Coconut milk
Coconut milk’s effect on your body’s pH depends on how it’s made. Fresh coconut is alkaline-forming, while dried coconut is acid-forming.

Oat milk
Oat milk is made from oats and is acidic. Grains such as oats and oatmeal are acid-forming foods, even though they do have other benefits.

Cashew milk
Cashew milk is acid-forming. It’s made from cashew nuts. Most nuts, such as cashews, peanuts, walnuts, and pistachios, are acid-forming foods.

Nearly 30 years ago, after recovering rom Pneumonia, I would get hives on my arms and legs every night. It would go away by morning, but it was miserable. That lasted for a year. No doctors were able to help me. They would just prescribe antibiotics, which did nothing (it was the 1990s when doctors would hand out antibiotic prescriptionsblike they were going out of style). One caring nurse gave me Calamine lotion, but that didn't really help. After a year, I would only get hives as a comorbid symptom to colds and flu. When I moved back home and got the flu and the urticaria (hives), my dad suggested stirring about 1/4 tsp of baking soda into a tall glass of water and sipping it. The hives disappeared and was not bothered by them again until years later during my first pregnancy. After a few days of it, I remembered my dad's advice and drank a glass of water with a bit of baking soda. And the hives vanished. I really do believe that the pH factor has something to do with it. When our bodies get too much acidity built up, our bodies react. Baking soda is alkaline. Milk is close to water on the pH scale, so I can understand that milk could also help. And milk can also relieve acid reflux. Most tasty foods are acidic, so it's common to be out of balance. Green leafies are alkaline, and we don't get enough of those. Thank you for sharing this. Most information online about urticaria is about infections, stress, and allergies causing it, I am glad to see this post involving the pH factor and its possible effects on urticaria. I wonder if I get out of balance when I have colds because of the fruit juices etc.,that I consume (and avoiding dairy in order to prevent mucous), thus getting out of balance. It also could trigger things. The pH is fascinating and it could have a complex effect on our bodies that hasn't been addressed enough..

Hey thanks for the baking soda water suggestion I’m going to try it!!
