Red spots on the skin is a very common symptom that can be manifested by many different medical conditions.
Someone may find red spots on the skin for numerous reasons, ranging from allergic responses to heatstroke.

Infections that may cause red spots on the skin
Some infections can also lead to red spots on the skin.
If a person suspects a skin infection, they should see a doctor.
Chickenpox or shingles
The chickenpox virus causes these infections, which cause red, itchy, fluid-filled blisters that can appear anywhere on the body.
Shingles occur in adults who have already had chickenpox. Shingles usually affect one area on one side of the body, according to the National Institute on Aging.
This contagious viral infection causes a characteristic rash of small red or pink spots on the skin.
The rash usually starts on the face and then spreads to the trunk, arms, and legs. Rubella infections also cause fever, headache, and swollen lymph nodes.
Meningitis is a medical emergency. It is an inflammation of the membranes that cover the spinal cord and the brain. It usually occurs due to a bacterial or viral infection.
Symptoms of meningitis include:
- stiff neck
- sensitivity to light
The rash doesn’t always appear. However, if it does, the person may notice small pink, red, brown, or purple stings on the skin. It will also not fade if someone rolls a glass over it.
MRSA (staph) infection
MRSA frequently affects the skin, causing painful areas of red spots on the skin. People may also experience pus drainage from the affected skin and fever.
Other bacterial skin infections can also cause painful and inflamed areas of the skin. If a person suspects they have a skin infection, they should see their doctor.
Streptococcus bacteria cause this infection.
These bacteria live naturally in the nose and throat. They cause a red rash on the neck, armpit, and groin. The rash consists of small red spots on the skin that are rough to the touch.
When to contact a doctor regarding red spots on the skin
If a person suspects a skin infection, they should always see a doctor.
People should also talk to their doctor if their rash does not improve despite over-the-counter or home treatments.
People should also seek medical attention if they have a skin rash with any of the following symptoms:
- severe pain in the head or neck
- joint pain or stiffness
- labored breathing
