I get both types of burning...the kind that radiates OUT and seems like my bones are made of hot irons and the kind on TOP of the skin that feels like someone has a blow torch and is using it on me. The pain on top is the stuff that I get SOME relief from with lidocaine cream or Lidoderm patches. Not a lot...but some. For me it's not caused by the sun though...it's my extreme sensitivity that causes the burning on the skin so it's more air movements and cold or just when the sensitivity is going nuts and the slightest touch sets me off. Desensitization has helped somewhat...but I still have really bad days too where I can't stand ANYTHING touching me. We all have different triggers though...so maybe the sun is one of yours...or maybe it was sensitivity from the heat on your skin.
