Thank you for your feedback regarding my allergies.
To be honest, I think everyone should have their allergies checked out, as it's obvious to me that your doctors are not taking these problems serious enough.
Quite often the allergy concerning nickel lies in the jewellery we wear and the food we eat. As for allergy to steroids, that is a more serious problem and could result in hip replacements, etc. (as in my case).
So the obvious solution is to keep pestering your doctor about side effects.
