Severe reaction to insect bites post radiation

RVH

I saw a post from several years ago about severe reactions and swelling when being bit by mosquitoes post chemo. Has anyone had the same issues with bites post radiation?

I had throat and neck cancer, TORS surgery and neck dissection followed by radiation. I did not have chemo, but did have 23 lymph nodes in my neck removed followed by 6 weeks of radiation. That was 18 months ago, since then I’ve had two severe reactions after being bit by mosquitoes. One on the neck and one on my jawline. Both times the swelling was about the size of a golf ball cut in half. Would love to hear if others have experienced the same thing and would welcome any advice. Other than not getting bit I’m not sure how to manage this.
