I, seriously, am a doctor.. vaccine is usually indicated for people over 60 years, medicare will pay for it then. You can get it earleir but wouldnt really reccomend it. Shingles, like chicked pox, is a herpes virus called Varicella. The only real treatment is if its discoved within 48 hours, and without delay, start Valtrex 1 Gram, three times a day,,,,The pain after the shingles are goine (dry, crusted over) is called post-herpetic neuralgia (nerve pain) and medicines are the older Neurotin tablet (three to four times a day) and newer ones called Lyrica (also, about three times a day.) but IS indicated for PHN. Hope that helps.
