My arms, back and legs burn terribly bad like a sunburn and feels extremely tight. hurts to touch also. please help. ?

Sunburn: Hello. I would try aloe gel and cool cloths on the burned skin. If this does not help or blistering develops, you should see a doctor. In severe sunburn cases, silvadene (silver sulfadiazine) can be prescribed which prevents infection and stops the pain. In the future, be sure to apply a sunblock (at least SPF 30) prior to sun exposure and re-apply if you are in water.
