I don’t know if that specific option is a scam, but I highly recommend going to an actual allergist. I went and did the skin tests but didn’t get much in the way of reactions, so they did a blood test and found a lot more allergies that didn’t show on the skin. From what I understand you can ask them for a full food allergy panel and they would test for the usual suspects, plus any they/you want to add in.

My sister did the blood test and found tons of food allergies she had no idea were issues for her.

Worth trying with an actual specialist who can tailor to your needs (and local allergens!)

When mine do this it can mean it’s getting too much sun and not enough water. Also not having enough humidity during the winter. You could get a lil humidifier to keep near it, and make sure it isn’t too close to cold windows or air vents!

I walked to the grocery store .2 miles away and back while still managing to be able to get out of bed the next morning without too much awful pain. I haven’t been able to walk that far in years.

I like doing chair yoga when I’m having severe flare ups! There’s some good youtube videos on it, and it’s safe for ankles and wrists!
