Hello Jane and a big welcome to our friendly forum! 

I hope you won't mind I have slightly edited your title so that other ladies here who have had a similar diagnosis and experience can spot your post more easily and share their own experiences with you. It sounds like you are doing amazingly 4 weeks post surgery and it's great you are keeping up with the exercises and noticing you are getting more flexibility in your arm every day. Onwards and upwards!

I hope everything goes well with your chemotherapy sessions - I can imagine it is stressful with Covid19 around. To help you prepare for it, I thought I would share this page from our website on chemotherapy for breast cancer. We also have useful general information on chemotherapy here which I hope will be helpful to read ahead of your first appointment. 

Best of luck with your treatment! I hope everything goes well for you. 

Best wishes,
