[borninabarn]

Hello Friends,
I guess I am not sure what to do?I was injured again June of 08.I have had these problems since 1993.I am in Ia.Many MRIs all leading to my back is worn out.Last nero said Degeneritive Disc as did the last one 4 years ago.I am on 120mg Avinza everyday and that doesnt take the pain away.I have been off work now almost a year again.DHS says file.Mother says file.I feel I should this time I should.Some days are better than others but I really feel like I couldnt make it a day at a job.I do feel like I need to do something soon.I was told they deny alot the first time?What are they going to look at or what do I need to show them that I am needing SSDI Thanks,Born
