Tessiah, Tessiah - 01/13/2014

they had not receive a reearfl. Here we go again, right? I had the Dr refax the reearfl again called to make sure they got it. When they finally found it, they said that now it would have to be scheduled for the Drs to review it and see if they would accept me. If so they would then send it to the nurses and I would be scheduled for an appointment. I had to wait to hear from them. Really???? So, I waited and waited Meantime I ran out of vicodin again, the dr at the clinic was not allowed to prescribe any narcotic drugs, go figure. So I went to the streets and found a man who would sell them for $2 each my boyfriend agreed to pay for them. By the end of June, after calling urology several times they finally gave me an appointment for August 9th I was relieved, believe it or not but had no idea how I was going to survive the pain until then. My son decided to take out a bank loan so I could go see a urologist outside the county hospital. I called to make that appointment and was given the date of August 6th. On July 1st my relationship of 9 years ended. My boyfriend moved out. Turned out to be a good thing, as I am able to manage the pain much better being alone, without any outside stress, and not feeling responsible to do any housecleaning or cooking or laundry. But also not being able to afford the vicodin anymore. by mid July I was back in emergency. they didnt even take me to the back just gave me more vicodin and said see your urologist I saw the first Urologist and although he was sympathetic and willing to do the surgery, even willing to wave his fee's for doing the surgery, he said the hospital would still want to be paid in cash before the surgery was done and that would cost around 15 to 20 thousand dollars. He gave me more vicodin and Ibuprophin, charged me 500 dollars cash and sent me on my way. When I saw the urologist at county hospital he said that my stone was in a good place for the shockwave surgery and that is what he would recommend but unfortunatly until my insurance came through they would not schedule the surgery either. I told him I had applied but he said It had to be approved. He scheduled me for another ct scan, some blood work and of course gave me another script for both meds, told me to come back in a month. They would send me an appointment in the mail. I had all the labwork done and when I got my appointment it was for October 10. Unbelievable, right? I was on the phone everyday with the insurance people pushing them to get it approved. By this time The meds are eating my stomach up and I am nausous all the time. I had to stop taking the meds. I am drinking water by the gallons trying to keep this thing floating so it stops stabbing me and am only moving from my bed to a chair staying as absolutely still as I possibly can, counting the minutes till my next appointment and in the mail I get a rescheduled appointment notice for October 31st I am literally at the end of my rope. I manage to get on the phone and told them point blank that I could not wait until the 31st I didnt think i would survive another day let alone another month. They moved it up to the 15th On October the 8th I received my insurance card. I called that day to make an appointment to see my primary Dr. my appointment is for November 14th Unreal, right? Am I right? Well I went to my urology appointment on Friday in a wheelchair. my appointment was for 2:45 they called me in at 4:45. The county hospital is a training hospital, so you never usually see a real Dr. only students at the end of their schooling, and never the same one twice. They see you then consult with the real Dr. somewhere out in the Hallville. This student was about to blow me off with more meds and scripts when I lost it. The tears started flowing, my emotions were right at the surface and she scratched it. Within minutes the real Dr. was in the room scheduling me for surgery. I did leave with more meds. Norco this time. and all my pre-op paperwork. I am scheduled for shockwave on Nov. 8th. Hope I make it till then. I guess the first Urologist had it right when he summed it up by telling me, unfortunately people like you just fall through the cracks . And it is sooo true people here are dieing everyday because we cannot get medical attention without insurance that we cannot get without working a job that even offers insurance and even when we do work at a job that offers insurance, if we get sick and cant work, we lose the insurance because we lose our incomes. So proud to be an ailling american. Sorry this was so long, and just think I havent even had my surgery yet.Whew' I feel a little better for having gotten that all off my chest though.
