I have learned from my personal filing, first time filing. Always request a hearing I did and when my hearing came up I had to lawyer all I did was gather all my doctor records and any test I have had done. Went in talked to the lady presiding over my case and told her the way things were and how they have changed for me. When all was said and done I walked out getting 5 yrs back pay and Medicare right off the bat. So it is worth the fight sometimes it is hard but in the end it is worth it. Hope this helps anyone that is looking for advice.
