first I have pain in my left upper back with numbness in the left inner aspect of the arm down to my wrist. went to ER, ekg & brain scan "okay". had MRI of the thoraxic spine & cervical spine were "okay".in the meantime I developed blisters with redness along my numb area & also on my left chest. I went to urgent for this & was given gabapentin & famciclovir. Am I on the right track?
Dear patient You have got herpes zoster on your chest. For which antiviral Chat Doctor.  Gabapentin is given for neuropathic pain relief. So you are on right medication. All the best.
