Sleep in the tub with cool water just warm enough to tolerate it with oatmeal bath and aloe in the water or it will hurt incredibly badly when the blisters pop and make you stick to the bedsheet. Been there done that now I make sure I carry my coppertone 45 with me everytime I go somewhere that I will be outside.
the liquid aloe Vera that comes in blue and green gel helps and you can refrigerate it as does solarcaine spray.
You can get some blisters after sunburn. Sunburn will show up after 12 to 24 hours of exposure, and treating this will definitely take some time. However ensure you keep it cool, moist and leave the blisters intact. For more details, go to http://www.mayoclinic.com/health/sunburn-treatment/AN01423.
I got sun burned a few days ago and i got some little blisters on my shoulders. They hurt pretty bad. Now my shoulders arw peeling. :( make sure you keep some aloe on it if possible, or some non sented lotion...i find the scented makes it burn
