I am so done with this, I have had this horrific burning, gnawing deep intense constant pain in my chest for now 3 yrs... been on every drug u can imagine (gabapentin, amitryptline, nortriptyline, topomax, lyricia, cymbalta and the list goes on and on and on Ive had nerve blocks etc.. If anyone has had anything that has helped them I would love to hear from you,,, shine
