New diagnosis, have had mastectomy

Hi TeePee, did they give you an information sheet on arm exercises?  I have been doing them since the day after surgery. Just bending and stretching and standing away from the wall and walking your hand up as far as you can face on and sideways. The stretching really helps. If its painful only push it as far as you can and then relax and just keep trying. It will get more flex in it over time. Mycarmpit was completely numb but I am slowly getting sensation back 3 weeks after surgery. It still feels wierd in the evening a partly numb partly sore sensation under my actual arm. I am pretty sure its nerve pain. I just take some panadol and massage seems to help a lot. 
We are definitely all different in how we recover. Even our individual stories. I too have been very positive about this whole thing. People keep saying it's okay to cry and looking at me with those sympathy eyes. I have seen my Mum go through this and lost her when she was 39. Shocking isn't it but I have been lucky to come this far unscathed. I always felt like this was the demon I would have to face one day. I am a very strong minded and stubborn woman. People think I am vulnerable but only when it comes to other peoples care. I believe while I can walk and talk I am going okay. 
I am sorry you are in a bit of pain. Hopefully that will ease with time. Make sure you tell your surgeon or contact your Breast Nurse they may be able to suggest things to help. 
I am seeing my oncologist tomorrow.
