Total hysterectomy done robotically 2 weeks ago. Pain very severe shaking chills no fever. Should I seek help?

Yes. You could be developing an infection. You should see your doctor asap.
Strongly yes. It is always to think the worst case scenario. In this case , post operative pain and chills ( most likely you have fever ) is due to infection . Contact your surgeon and let him know what you are experiencing. He will help you.
