First of all, you should know that Disability ALWAYS denies first claims. It is a practice of theirs in the hopes that no one will appeal. And I think that you should definitely appeal.
They give all kinds of flimsy reasons why they deny our claims. I don't know too many who have won disability on their first claim. Almost everyone who has gotten disability has done so on appeal.
Don't give up! Appeal the decision and be prepared to fight with them! It is not going to be an easy fight, but they are going to make you fight. So, be strong...stand up and fight!
Peace and Blessings
Look For The Good and Praise It!
