Anyone have weird reactions to colostrum ?

I tried two different brands they both made lymph nodes swell around my body then shrink like on and off between hours of eachother. But then also made my lymph nodes in my neck stay swollen for like 6months I only tried the colostrum for a week but then the lymph nodes in my neck stayed swollen for ages.
I also got hella itchy legs.

I do have Mcas but these r not my symptoms I get with it I eat everything still despite my Mcas symptoms and the symptoms are tachycardia and low bp with also heating up.
