If the lizard you eat has no toxic side effects and you have no discomfort yourself, don't worry at present. I'm really worried. I can go to the hospital.
Whether the hand bitten by a lizard is poisoned depends mainly on the symptoms now. If there is a wound on the bitten part, and the skin turns black and red, the pain may obviously be poisoning. Cleaning with soapy water may not be very effective, and most cases should not be serious. You can take anti-allergic drugs prednisone and vitamin C. If you have serious symptoms, you'd better go to the hospital for treatment.
