Any tips 4 covering scabs/ picking on lower arms?

I don't pick @ my face anymore. But, I've gotten to where I pick both my lower arms (wrist to elbow) so bad that @my best of times I have at least 10scabs per arm. I've tried switching to my upper arms, legs, or other places where it can't be seen but I can't. I am a med student & a liscenced PA. It is causing problems @work. Patients think I must have some type of skin infection or something, etc. Anyway, does anyone have any tips 4 trying to cover the scabs on my arms& make them less noticable. I also live in S. FL so long sleeve shirts are not an option on a regular basis. Thanks alot
