Need Help with Pain Management

I’ve noticed that the cold makes my body hurt worse when going through a flare up so I bundle up and keep as warm as possible. Then I either tune the heater up in the house or use a heating pad. I also have recently started to massage the areas that hurt with icy hot or something similar to it, and it helps so much. When the heat isn’t helping the icy hot is what I turn to. I rub it on my skin and within 2 minutes I feel relief
