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.
Other possible causes of thigh numbness include problems with nerves that connect to the lateral femoral cutaneous nerve. For example, nerves in the lower back connect to the nerves of the thigh, so disc disease that compresses nerves in the lower back may cause numbness in the thigh. It's likely that your doctor can find out the cause of your numbness just by reviewing your symptoms and performing a physical examination.
