Give yourself time. I had my surgery - lumpectomy - on 11 July so a month before you. I still get some pain but I think it’s more doing too much! I’m still not back into much exercise - just daily walks. I usually do yoga & Pilates and hoping to get back to that next week - I have a good range of motion and no pain but worried about weight bearing on my shoulders doing planks, push-ups etc.
I had radiotherapy in my 40s and it made me really tired so I took sick leave for that period. I’ve been told it affects you more the younger you are! Hormone blockers are OK - they just bring on menopause early.
I got my biopsy results 2 days after my surgery but depends on your surgeon and if you’re private or public. Wherever you had your surgery you should be able to talk to a Breast Care Nurse - they are invaluable!
