Thank you for the reply.
The symptoms you have described of bumps on the lower left side of abdomen, another on upper thigh and recently on your back near left arm is suggestive of a condition called acne.Although typically on face,they can appear on any part of body and at any age.
When you are sleeping,these get rubbed against bed & due to friction they get popped up & slight blood is discharged which you need to clean(first aid).
Another less likely possibility is of folliculitis.It is inflammation of one or more hair follicles.the damaged follicles are then infected with the bacteria staphylococcus.
These acne needs to be treated.The aims of treatment are to prevent new spots/bumps forming, to improve those already present, and to prevent scarring.Apply ointment containing bezoyl peroxide like clearasil Max.It has antibacterial effects and can dry out the skin and encourage it to shed the surface layer of dead skin.It is available as over the counter(OTC) without prescription.
Also you may need oral antibiotics & other medications.So I advise you to make an appointment with your dermatologist for examination & hence the prescription medications accordingly.
Till then apply ointment containing bezoyl peroxide like clearasil Max.It will help you greatly.
