It seems like you are having Papular Urticaria
, which is a type of urticaria caused by insect bite or even by the left overs of the insects like fur on their wings or on the body.
So thats not a seriouse problem.
I would suggest you to start using
1: tablet loratidine
10mg once a day for seven days
2: 1% Hydrocortisone cream
on the affected areas one to two days for seven days.
And hopefully it will settle down.
All the best.
