Kara I know it is difficult to ask for help and sometimes more so from friends then strangers.
Here is a suggestion that may work for you. Do or someone you know like a close friend or relative attend a church regularly? I have seen these folks come thru many times with offers to pay the pharmacy when someone needs a med that they have to have and as a CPer this is certainly the case here.
They do not have to know what med your filling so it wont violate your privacy as most generally want to know if it something that you need or is going to effect your health if you dont get it.
Almost all churches have benevelont funds for doing this kind of thing and if you do attend or belong to one please call them and ask them if they have funds to assist with you with this,if you dont ask someone you know who attends somewhere regularly if their church has such a thing and go from there. You certainly do not need to have to go thru w/ds as pain due to the inability to pay for your meds.
Most of the organizations based locally have the need to know what it is your filling and they almost all will not fill pain meds nor nerve meds for some reason.
Good luck to you!
