This sounds more like irritation than anything else. I can't think of any association with your symptoms on the right side of the body, the right thigh, or the chest. I also can't make much sense of the "large bumps." Basically, you will need to see a doctor in person for this. meantime, avoid applying anything medicated. Use only non-medicated moisture lotion, minimize friction, and make an appointment.
Take care.
