Hi @ade66
Welcome to the forum.
You may also want to join other lovely people having chemo at the same time as you, it can be very supportive to share your experiences and side effects. This is the link for July 2024. Reading previous threads can also prepare you with what to expect.
There is so a thread for us HER2+, it started last December and is still ongoing as many have between 6-12 months of Herceptin or Phesgo (Herceptin and Perjeta).
www.lookgoodfeelbetter.co.uk do a hair/scalpcare course with Jasmin from www.cancerhaircare.co.uk which lots provide online and by phone.
I’ve now had 15/18 Herceptin injections, some sting more than others. The nurse that did the last one said it’s best to inject a little bit and then wait for the numbing from the local anaesthetic to kick in and then continue for 5 minutes. It was the least painful of them all. So many ask them to do this next time, it might work out less painful for you as well.
Hope this helps
