Hitting your little brother over the forehead with a lamp
There are many reasons why you might have painful bumps on left side of scalp. These could be bug bites.
Your scalp is probaly irratated. You might want to wash your hair more often. I wouldnt try to pop the bumps like a pimple either because it could just irratate the scalp. Ive had large bumps on my scalp and after I gave it a good wash it dissapeared after a week. So all you have to do is wash it really good and if that dosent work just keep washing. Also if you keep growing bumps on your scalp you possibly might be growing lice, but its rare when you have bumps. So really all you need to do is wash it. (:

The scalp could be red from rosacea or an allergy to shampoo.
Poor hygiene?

First, there is no single vertebra that affects hair follicles. It is possible that if your spine is unhealthy then so will be the rest of your body, and ultimately this could affect your hair follicles to some extent, but the bumps and sores on your head are most certainly not a result of spine health. A doctor of chiropractic is not the right specialist for this problem. Doctors of chiropractic specialize in the spine and general neuromusculoskeletal function. This sounds more like a fungal infection (tinea capitis perhaps?). This is likely a condition best left to a different type of specialist known as a dermatologist. Make an appointment with your medical doctor to get a professional opinion.
