Lidocaine
"Watson/Actavis (now Teva) Lidocaine 5% pain patches have been very helpful in dulling the shingles-like pain that I live with 24/7.  As noted above, when you hit 65 you are out of luck because that's when the FDA approval for only one usage is enforced.  To purchase these without insurance will cost as much or more as my monthly Social Security "income."  Age discrimination, plain and simple.  I will continue to fight to get the only topical pain relief that is effective and doesn't cause a rash."
