I received Taxotere which brought about the same symptoms. It was like my legs weighed 200 pounds each and I had a hard time walking. Eventually, I got edema which made it even worse. Once my regiment was done, it got easier.

Hi Sabra, Are you still on chemo? Are you taking an oral chemo like Arimidex? I had problems with my legs and energy when on Arimidex. It is important to walk so as to prevent other complications. Take this up with your family doctor or oncologist. Ginny

Low Potassium will give you those symptoms. Good Luck and keep us posted. Ginny

@A MyBCTeam Member yes, I am still on chemo...have 2more chemo cocktail treatments. I am also receiving Herceptin every week! The "fatigued legs" just started @2weeks ago...I'm guessing its just another side effect for me! I intend to bring it up on Tuesday! Forgot to tell you, my potassium level is low...but I am on oral potassium! I'll keep you posted on what Onc. tells me!
Thanx 😊
