I have been itchy for 1 week know. Always different areas on my body. Bottom of my feet, then palms, then inner thighs, never one place together. It's like one area then another. Itches like crazy but I can't see a rash till I scratch. I'm on penisilan for it 2 tablets for the last 3 days but it's not getting better. I've been taking hot baths, but nothing's working. I will be itchy for 2 hours then nothing for 4 hours it's so random. Help please
