Rash all over body

Yesterday morning i woke up and was very sick to the stomach.  I go to work anyway.  I am currently working away from home and have been living in a hotel for the last 4 weeks.  I get back to the hotel and go to bed.  I slept for around 12 hours. During sleep i would wake up a few times because my legs were itching.  I woke up this morning and i noticed a rash pretty much all over my body.  The back and front of my legs and my groin area is were the rash is most intense.  It is also on my chest and faintly on both of my arms.  The rash doesn't itch at all.  I am thinking its possibly a severe form of heat rash.  Any help is appreciated.

Mostly a viral rash.Apply calamine, and cap benedryl 1 at bedtime should be back to normal.If persists do consult.

One more thing.  I did wash my clothes sunday in a different detergent than i normally use.  Could this cause the rash also?  After watching it today it isn't getting any better or worse.  I think i may re-wash my clothes and see what happens.

Thanks for the advice jegesh50. I will get the calamine tonight after work.

Detergent induced ,possible but unlikely.
