Hi S.,
Do you feel engorged? I've self weaned 3 of my 4 children, youngest is still nursing before nap and bed and never experienced engorgement because it was a gradual process. Things could be different for you though.
I was in a car accident a year ago this past July. I suffered severe whiplash and worked with a chiropractor to get back to feeling normal. Since the accident though, I've noticed that if I sleep on my left side there are times when I wake that my right hand & fingers are numb and tingly. Chiropractic adjustments have helped to relieve this for me. However, I wanted to suggest to possibly see a chiropractor to clear any interference.
Hope you find some relief.
Peace,
J.
