My friend has these unusual bumps on her legs that kind of look splochy and she thinks its bug bites but it looks much worse than bug bites and she says there extremely itchy. Does anyone know what they could be?

It's a sign that your friend needs to see a dermatologist. Certain bug bites if left untreated can cause major problems later. Also alergic reations can happen at any time and those too can cause problems.

Its best to let a professional sort it out. And next maybe a good pest control professional.

'Extremely itchy' in the summer time often means poison ivy, oak, or sumac.
There are treatments at the drugstore, if you can't afford a doctor or get to see one right away.
I once slathered Solarcane (a sunburn lotion) on poison ivy and wrapped my legs in gauze for 3 days and it was gone. But some people are very allergic and need cortisone shots.
