The only problem I ever had with epidurals was they went to far and caused spinal leakage. This caused severe headachs when I stood up.
The body is completly interconnected, sometime when I stretch my calfs I get a tingling sensation in the back of my neck, go figure?
I could only think that so many enjections can't be good for you but that is just me. I would listen to your body, if it seems weird or feels weird, I would look into it more. Take care
