Hi,
Sounds just like me....I was on herceptin for a year until June 2011 and my right food tingled just like it was asleep or it felt as though there wasn't any blood going to it, very strange feeling. Once I stopped herceptin it went :-) I'm now on TDM1 which has herceptin in it and it's back again! Funny as it's my right foot again but worse and I feel it more when I'm lying down and sometimes to the point when I'm on the sofa I have to eleveate it which helps. Is yours when you are lying down? This feeling is common when on herceptin so try not to worry but as we all know cancer can present itself again and you must get everything ruled out for peace of mind... Although it was never discussed that my tingling could be brain mets but I know why other people are saying rule this one out. Hope it turns out to be just herceptin side effects.
