I'm A 37 Yr Old Female. I've Only Had Cold

I'm a 37 yr old female. I've only had cold sores a handful of times in my life. 3wks ago however I had a small cluster in corner of my mouth. Not that had. Then they showed up all over- forehead, cheeks edge brow, all along my lashes lid, neck behind ears and chest, Tiny, looked like pimples but had the same pain and sensations as those in my lips.Went to dr, given and took while rx and2days later they are not gone and I think worse!!! I have smoked meth for 2months and have stopped. Could that be the cause? Please help...
