While the legislation’s text hasn’t been submitted to Congress’ website yet, Gillibrand’s news release specified that the prescription limit was not meant for patients with chronic pain but for those with acute pain, “such as a wisdom tooth removal or a broken bone.”

But disability rights advocates ― many who responded to Gillibrand on Twitter ― noted that the line between acute and chronic pain was not always simple to determine and that acute and chronic pain often overlapped.

“The distinction between chronic pain and acute pain isn’t nearly as neat and tidy as the Gillibrand and Gardner press release indicates,” Matthew Cortland, a disabled, chronically ill disability rights lawyer, told HuffPost. “The patient community knows that for many living with pain, it can take months or years to get a correct diagnosis of chronic pain.”
