If the pain your husband had is neuropathic pain (which can affect people after shingles) then he is on a low dose of Lyrica at 150 mg a day. I have neuropathic pain and it was only when I was at 400mg a day that I got any pain relief. The max dose is 600 mg a day so maybe your husband should talk with his Dr about upping the dose until he finds a daily dosage which offers him pain relief.
