Panicy Hamster

Question
My hamster has been super panicy and restless the last two weeks or so, she gets out daily in her ball, has access to a big enough wheele and has a large cage but she is constantly running back and forth like shes pacing, climbing up and down her cage, stuffing her cheeks then emptying them then re-stuffing them and moving it, run on the wheele then back to pacing and climbing, up and down her treehouse etc... also if I approach her cage she flips around and glares like she wants to attack. She has also chewed through the metal part on three different water bottles in the last week even though she has proper chew sticks and toys. None of this is normal for her.  I have gotten to the point where I dont want to try and pick her up any more for fear she will either jump out of my hands or bite. I even have a hard time trying to feed her now because she acts like she wants to attack. I have had her since she was a baby, shes now about a year and a half old. She has been socalised properly, and never had any tramatic experiances. I honestly dont know what to do with her now. Any advice would be great. Thank You.  

Answer

     I have no clue what this could be this is vwery abnormal behavour for a hamster. Especially one that is well socialized. I would take her to a vet to see if she is sick. One thing might be she is going blinde. that would explain the panicy jumpiness.

Let me know how it goes with her
