<s>[INST] a few days ago my eigth year old son had a couple of bed bug bites on his penis which are healing. but today he has scrotal pain. his testis are tender. the right one looks like it has a swelling of fluids, and the left sac is thickened and red. he does react badly to insect bites and swells up if bitten by mosquitos. my son is not immunised. do I need to take him to the doctor/hospital? he is not feverish and otherwise well and active. [/INST] Hi thanks for asking question.Here is some treatment modality for your son.With soap and water area has to clean properly.Application of ice pack and cold compress relieve pain and swelling.Baking soda paste can be applied over it.After bite topical ammonia helpful.Topical steroid cream and oral antihistaminic is helpful.If your son suffer from fever and bite site seems to be infective then antibiotic needed.If with even steroid and antihistaminic swelling not decreases and not improving then refer to doctor for starting antibiotic.I hope i have solved your query,thanks </s>
