spots and hives on my body

[THE-INTROVERT]

i keep getting spots and hives and pimples around my body especially on my back well mostly on my upper back could this be linked to no exposure to sunlight i havnt had my curtains up in days either

No it cant.. but you should get atleast 10 minutes of sunlight a day

but it can be caused by sweat.. are you sweating alot on your back and also if you have long hair.
