Welcome to HCM.
This is suggestive of tick bites which could be causing allergy
and swelling. I suggest you apply calamine
lotion on the swollen area and take Tab Atarax
three times daily for 3 days. I also suggest you check your bedding and linen for tick infestations. If this swelling does not reduce in three days, I suggest you get a skin doctor's opinion and appropriate therapy. Thanks.
