Went to see the woman today and she said she'd like to do this on me which she did for about 45 minutes. She just touched the places where I hurt most and said it shouldn't be painful. It was in some places even though she was really gentle but, I do feel just slightly easier tonight. My shoulders aren't as painful either. I'm going back next Friday and will see if it makes any more difference then.
If not I might ask her to try something else and see if that works. It's £35 so can't go too often
