I'm using two but one is so expensive it's hardly worth mentioning. The other is not expensive and is covered by my insurance.

DICLOFENAC SOD/LIDO/PRILO (C) 5/2/2% LIP

Used for pain and muscle spasms. It's anti inflammatory. It works to some extent and better over time and consistent use.

The other has 30% Ketamine which acts as a nerve block. It's hella expensive though and I really can't afford it for large areas of my body. For small areas it's doable. But if you needed it for a lot of your body it would cost easily over $100+ per day.
