I went to therapy and it stopped it, so I'll say therapy Works

I had mastectomies and 11 lymph nodes removed. Yes, my arm hurts and I believed it's due to nerve damage
I had limited movements due to my drains as well. Before I was discharged, my ot had me do some exercises and it did a lot. By the time I see my ot, I have good range of motion. Ot and exercises that they told me to do helps a lot. Watch out for lymphedema, if you notice your arm swelling, call your Dr asap so it can be treated right away. Hope you feel better soon. Take care.

Wishing you all the best as you look for the cause of the pain, and a way to get relief. Since you had shoulder problems before- have you ever had physical therapy? Perhaps that might be a route to consider to work on that range of motion, etc. Hope you start feeling better soon! Hugs!

It’s been 5 months since I had a single mastectomy with seven lymph nodes removed on my right side. I do not necessarily feel stiffness in my chest, but I do have severe pain at times in the top of my shoulder with certain movements and positions. I had some mild shoulder issues prior to surgery, but it is so much worse now. I’m not sure of the positioning of my arm during surgery, but I can’t help but think that was part of it. Limited range of motion, pain when reaching up or out to the side, or across to my left side. It’s difficult to put deodorant on the opposite side or wipe myself (TMI!), and nearly impossible to get my bra fastened. I know, I could fasten it in the front, but I’m stubborn and think I need to be able to stretch that way.
After 13 PT sessions, it seems to be worse instead of better. X-rays show only mild arthritis.🤦🏼‍♀️ I’m sure there’s more to it than that. I’m in the process of trying to get further imaging.
