Rashes and itching all over the body can be due to eczema,dermatitis,fungal infection,scabies and various other skin infections.It is impossible to guess the cause without a physical examination of the rashes.
I advice you to meet a dermatologist soon.Till that time some tips for you:
1.Wear loose clothes, especially ones made of cotton.
2. Calamine lotion will help in skin irritation, bring down pain, inflammation and also gives a soothing effect.
3.You can also apply Aloe vera which would give cooling effect.
3. Avoid scratching the lesions.
4. Avoid direct exposure of the lesions to sun.
Early treatment will avoid scars,so do not delay visiting a Physician.
