If these spots hurt and they feel like pulling inside and are still not healing, then tell your mum how it feels. As you live in a hot country you may have been bitten and this got infected. It would be wise to see a doctor because normal spots to do give you pulling sensations.
If these are boils and abscesses or an infected insect bite, they need antibiotic treatment because the infection can spread inwards.
I was 11 when I had my first abscess on the inside of my upper thigh, started off as a very small spot that got worse.
Best wishes.
Thanks but my mom isn't really taking it seriously,and my skin doesn't really heal well since I was a baby, it takes really long to heal . Should I be worried?
As you have never had sex, then you do not need to worry about STD.
I would advise you to see your doctor so that he can examine these for you. As you are feeling like a pulling sensation, it sounds that it may have become a boil or an abscess and you will need an antibiotic for this. Possibly some drawing ointment if they do not have any open wound or the doctor may also need to drain them.
Make sure you see your doctor, because infected spots/boils and abscesses can spread the infection inwards.
Best wishes.
