This could be infection of the ha follicle or folliculitis or some bacterial skin infection or pustular acne.
You should not pick or poke at the lesions - it would get secondarily infected and the infection could spread too.
You need to wash the areas several times with fresh water. Do not use any cosmetic products on his face and use a medicated sunscreen whenever you go out.
Apply calamine lotion at the site of the lesions and see if it helps.
It would be advisable to consult a skin specialist for your symptoms and a proper clinical examination.

I know this is VERY old but worth a shot... Did u ever figure out what it was? I think I have the same thing- my chin is very inflamed (from the ends of my mouth down to my chin) as well as under my chin (it kindda looks like I have a double chin but I know that's not it...). I noticed this after I shaved my goatee off that I had for about 3 months. It's been about 6 months since I've shaved it and it still hasn't gone down.... Oh also, the inflammation seems to be a bunch of tiny inflammations under my skin- like bumps
I ahd 5 apear on my face last year, when I went to see a dematologist we found out it was caused by a bacteria called stapphylococcus aureus and then when more appeared after a course of penicillin, mine were foirming because I have a allergy to penicillin.
I know they have said not to touch the lumps, but I found washing them in hot water and gently easing the core out of the lump was the best way to get rid of it. I gave up going to the doctors to get antibiotices as it just didn't work...hope this helps
this is weird, i have had a problem with a swollen chin/lump ever since I tried using a sonic face cleaner. to me it felt as if the bristles had punctured my chin and dirt/makeup on the bristles got under the skin. I went to the dermatologist 2x and my PCP, they seem to think it is irritation. It also gets itchy. and so does my jaw/neck area under chin. i also have itchy skin on chest/thighs and not sure if it is linked to the chin issue or otherwise dry skin. this has been on-going for 2mos. i have tried gentle cleansing/moisture prdts. cortison (script). metrogel from derm dr. it calms down and then gets worse but never goes away. I see a white mark on my chin and when swollen it feels like a hard lump under the skin about a 1/2 inch in size.
