I am Dr Fahim and I will help you with problem
I have gone through your question and under stood your concerns. Mostly likely it is a
allergic reaction to tick bite, resulting in
skin inflammation of the scrotum. Tick bite unlikely causes infection of the testis, which lying inside the scrotum. You need not to worry, it simple and treatable condition. All you need to do is to keep the area dry and clean, apply
betnovate ointment (Local steroid ointment) twice or thrice daily, take
paracetamol 500mg thrice daily for pain relief and use scrotal support. He will be better in matter of days. If the swelling persist beyond three days of starting this treatment, then he might need to see a GP or a
general surgeon to assess his condition and get antibiotic coverage.
I hope my answer will help you. Do rate it, if you like it.
