question: Hi Dr.Grief I had some bad skin rashes from diltiazem and warfarin. I am off these medications but the skin rashes left me with major itching. I have suffered with itching and smaller rashes for over 6 months. Lately because of some scratching on my back I developed 2 infections. My Dr. prescribed cephalexin 500 mg apx. Am still taking 4 tablets per day and the pussy infections are just about gone. Do these pills also cause itching and skin rash? Because I ve developed new rashes on my left shin and terrible itching at night. I take oatmeal bath before bed time and use Curel lotion. Also have used cider vinegar diluted to 10:1, sea water, chamomile tea. I have rashes every night. Wake up every hour and are terribly sleep-depraved. Also used Alo vera last night. An answer would be soo much appreciated. Thank you very much
