Yes, all the symptoms you are experiencing are from Herceptin. This wonder drug sometimes is a pain to deal with but is still a wonder. It's kept me going for the past 9 mo. If my ins co would just pay for all of it, that's another issue.
I have constant runny nose, insomnia, joint pain, pain in feet at night, had acid reflux before but it's gotten worse, think that's enough. But I deal with it and try to keep going. Hope this finds you doing well, you've had a lot to deal with.
This is my 2nd episode of Bc, other was 11 yrs ago. But totally different types of tumors, the latest was much more aggressive.
Keep me informed of your progress.
