Affects after mastectomy. What's normal?

Thank you very much for your replies as that was my first post ans I only joined this group this morning. My pain is bareable. I have been going back weekly for wound checks as my wound got so gross. I see my surgeon again next week. I just found out yesterday that I won't be needing chemo. I'm not sure what the triple negative means but I know I hadn't grade 2 invasive lobular bc but oestrogen and progesterone (she has written yes) as you can tell I am still knew to all of this lol I do think you are right about the weather playing a part of it. Because I have noticed that it is worse when it's cold and when I'm in bed. I have movement but just thought I'd be back to normal by now. I propably have up to 85% of movement. I found out yesterday that I won't need chemo or radiation. So I guessing that's good. They have just started me on something called tamoxifen. I'm having my first night back at work tonight. Fingers crossed all goes well. Once again thank you all so much for you really replies xx
