Ouchies!! I remember going to a waterpark last year and falling asleep in the sun for two hours. Once I realized how burnt I was, I couldn't walk for a week. 🙄 The tan line is still there!! I feel your pain. 😛
Anyways, apply aloe vera frequently, which should take some of the heat down. If it's super bad, try dabbing vinegar on it. As nasty as it sounds, it heals the pain slightly. 🙂
i live in florida... the sunshine state... so i get the sunburn at least once a summer (skin cancer here i come!) i actually have a bottle of lidocane lotion. it has litocane (not sure on the spelling) its a lotion that will get the burn out using the standard lotion crap you usually get but it has lidocane which will relieve the pain... at least you won't feel it as much and it does help go away faster... as a matter of fact my skin is peeling from a sunburn as i write this.
