welcome to my world. this exact same thing happened to me and my beardie. i thought it was just a phase and stoped handling her( yours may be going through a phase if it is, getting used to you will help it through a little). big mistake. the next time i needed to bath her i tried to pick her up and she drew blood from my palm. hold you beardie for about 5-10 minutes about 3 times a week. when you are holding him let him perch on your shoulder if he wants and so forth. but dont let him run wild. when picking him up gently scoop him from underneath with both hands. one hand in front of the front legs one in front of the back legs. also while your holding him make sure that his feet are all supported. if doing this make the problem worse then hes probably going through a phase and you should keep handling to a minimum.
