Ingrown toenail medication making pain worse?

Question

A few months ago, I had an ingrown toenail and tried to treat it with Dr. Scholl's ingrown toenail medicine. It's a cream that you put on the affected area and covered with a special bandaid.

I put the cream on and went to bed. I woke up a few hours later because my toe was throbbing and hurting horribly. I immediately stopped using the cream.

My nail is fine now, so this is NOT asking for an ingrown toenail remedy. This is just to satisfy my curiosity. Does anyone know WHY this medicine would make the pain WORSE? The only active ingredient is sodium sulfide (1%) if that helps.

Answer 1

Could be a reaction to some of the inactive ingredients in the product.

Answer 2

It was probably the pressure from the band aid.
