When I stick my glutes, I swear the oil presses up against a nerve & causes varying levels of pain in my low back & going down my but into my legs. Any one else experience this? I have a TON of scar tissue in my glutes; when was younger(22 in '98) I used the same 18g needle; once a week for months. I did the same with a smaller needle 3x's a week a year later.
