It would not hurt to see a dermatologist about this, it sounds to me like those little lumps could be some ingrown hairs, or maybe even some insect bite that you may have gotten while you slept. Either way, I would check to make sure it is nothing serious.
It could be swollen lymph nodes, but see a doctor if it continues. If you are really wanting an alternative therapy, bromelain with quercetin may help. These reduce pain and swelling, if you take enough (1000 mg of quercetin, 300 mg bromelain is good for me). Fresh pineapple is good too (bromelain is pineapple enzyme).
Try 1000 mg of Lysine with this. (amino acid)
I suggest you see your doctor.It could be nothing but have it looked at
