It is true that there is cross-sensitivity between a grass allergy and psyllium husks. The symptoms are certainly consistent with that.
Getting tested for the specific allergen can be considered. If you are indeed allergic to the psyllium, avoidance is the primary treatment.
I would discuss this with your personal physician.
Followup with your personal physician is essential.
