I have some sort of bites on the inside side of my leg that are itchy and have been there for 3+ months, how can I get rid of them? What are they?

Insect bites. Insect bites usually heal long before three months. Perhaps you now have a secondary prolonged reaction. Try applying cortisone type cream or ointment. If lesions persist or worsen, see a dermatologist for diagnosis and treatment.
