Foot pain made worse by products that are supposed to help

Some years ago I was experiencing foot pain which made standing for long periods painful to say the least. Reading about a product that you put in your shoe to ease such pains I experienced an increase in the pain almost as soon as I tried to use them.

Removing the inserts helped a bit but for days there were very sore and tender spots all over my feet. Massaging them helped but the added pain didn't go away for two weeks.

Anyone ever have a similar experience?
