As a home inspector, I would have charged even more. The real question, is what is it going to cost you to repair what the home inspector didn't find, because you when with the cheapest guy. Ask for references, find a home inspector who is fair, and thorough.
Friction can happen when the thighs rub together. The friction results in irritation of the skin of the inner thighs, leading to bumps on inner thighs. The irritation can cause a heat rash called miliara. Irritated skin often leads to blockage of the sweat glands and the formation of pink, red or white bumps. Common symptoms are itching or a prickly feeling in thighs.
I feel your pain. I too have a lot of inner thigh cramps that occur when I am sleeping in bed and decide to turn over. I have even got them on both thighs at the same time. These inner thigh cramps happen when I do a lot of walking or a night after dancing is guaranteed to get them. What works of me is when I get them I immediately have a few swallows of dill pickle juice. I know it sounds crazy but it works immediately.
