Panettiere Was Dealing With Health Issues Before Passing

Page Six spoke with Hayden's hairdresser and good friend, Erick Orellana, following her death. When speaking with the outlet, Orellana revealed that the actress had been dealing with back pain that was "really severe." Sometimes to the point that it became "hard for her to move her legs."

The outlet also spoke with another source close to the actress. The second source said that they also noticed a change in Panettiere's behavior.

"Earlier this year, she did seem a little tired at times. But she was a night owl, and... she has a lot on her plate," the source said.

The source also said that the Scream star was suffering from anxiety and was taking medication for the condition. However, one of the side effects of the medication was that it would impact her speech.
