Hello, I looked at the previous discussions on this topic and didn't really have a great answer. I had someone reach out to me today asking if dry needling the arm (shoulder/upper arm) would influence or help with lymphedema. I will be honest, I don't know any past medical Hx like if they had mastectomies or other significant reason for lymphedema. It was in passing that this question was posed. 

From the other discussions, it looks like it is ill advised. If I did perform anything, I would focus on the neck, follow the neurology of C5/C6?

Thank you for any advice on this question.
