The heel products are homeopathic.
They are ultra high dilutions of substances and do not have "side effects" in the normal sense.
If you are a sensitive individual, you might prove one of the remedies in the product.
In other words, a remedy that evokes an energetic response in a sensitive individual [proving] would do this temporarily...if this were the case, an anti-dote such as a cup of coffee, or inhaling vicks vapor rub, would antidote the remedy and stop the reaction.
This is true of an aggravation of existing symptoms as well.
If none of this works..it is not the heel and other causes need to be investigated for the headaches.
Any new headache should in fact be evaluated by exam.
