5 months out, your probably not in high histamine mode anymore. I have never heard of scalp burn being a side effect, but I have also heard that Xanax takes a bit longer than Valium and Clonazepam to heal from? I feel so bad you are going through that. I think what you probably need to do is take CBD Oil and see how it goes for a few months and that may bridge the gap to the healing. No doctor will tell you that though as they want to throw scripts at ya. I was told by my doctor that CBD won't help but I drove to Colorado and stocked up on it and it FOR SURE has helped me. I mean, you don't need a miracle, but you need a bit of relief, and I think it is worth trying for sure...
