The court provided guidance on the issues of evalaution of objective medical evidence and consideration of obesity:
"While the ALJ did sufficiently develop the record with regard to the Avery factors, she did not adequately explain either her application of them, or the reason for disregarding any of the evidence supportive of plaintiff other than her disagreement with the objective medical record. Specifically, the ALJ cited mild MRI results and the fact that none of plaintiff's physicians recommended surgery as the basis for her determination. However, as the relevant authority directs, a disconnect between the objective medical record and plaintiff's testimony merely starts the credibility analysis; it does not conclude it."
"...While the ALJ did add obesity as one of plaintiff's severe impairments at step 3 she did not address the effect of plaintiff's weight gain on her condition and, by extension, her credibility. The ALJ noted that plaintiff was 5′ 2″ with a body weight of 200 pounds. This weight gain certainly corroborates plaintiff's accounts of the effect of debilitating pain on her emotional well being and ultimately on her everyday activities. Nearly every physician in the record also noted that plaintiff had a muted affect and was suffering from depression, and its onset coincided with her injury and progressively worsened."
