I’ve basically been letting the grass in my back yard grow all spring. Cut some paths through so my small dogs could easily navigate and small patch for my senior dog.
Then I saw the foxtails I thought I had killed were back. I started cutting the grass so I could get better access to the foxtails and my allergies went crazy. Instant runny nose, eyes burning, etc.
This has really dampened my enthusiasm. (/rant
I’m sure that it can get better, allergies tend to be auto-immune and age relevant, since we know cat and dog hair exposure at below the age of 10 significantly reduces children’s future risk for fur related allergies.
From my own experience, I’ve overcome minor nightshade allergies before through cold showers, runs and exposure through gardening work before and found that with enough consistent exposure, after the initial flare off, I definitely grew at least a short term resistance to it, enough to not respond again for another two to three whole years
