This is exactly what we are dealing with starting March ( spring season ). But ours is more of allergies symptoms accompanied my mild tics! We are also falling sick again and again since March !
Also last year her tics got noticeable around the same time !
According to our doc this could be mast cell activation due to histamine intolerance ! Root cause - Mold toxicity !
Do you have any allergy symptoms ? Or just tics ?
We were asked to eliminate few high histamine food and introduce Quercitin and DAO enzymes !
