I've found new kratom to vary based on what state my body is in when i get it so I have reacted pretty strongly to white before when I was having insomnia and I was a bit jittery already but I would always kind of adapt to the strain and change my dosage so my body gets used to it after a day or 2. But I am always itchy every time I take kratom tho thats normal mark of good quality to me. Your reaction does sound pretty out there to me though I've never had hives or swelling though. My eyesight
