I have many and varied allergies (metals, plastic, rubbers, toiletries etc - I get a rash or blisters that generally go with a good antihistamine)
Everytime I have gone for any scan with contrast. They have said I can't have it because I might be allergic to it
So MRI booked - do I keep quiet this time and not mention my allergies (take an antihistamine before) or do I have yet another scan without the contrast and worry that they can't see everything properly (again)
