Charlotte who ? ' I ' m drawing a blank on a single unit who would be able to provide those , though . BB on spark would be pretty important in combination with all the rest , yeah ? <| sep |> Saffron For Pink ? <| sep |> Your thigh can potentially be sore afterward but mine are always fine , each time I switch legs for the injection . The only time I have any pain is while pushing the needle in , once its in I don ' t have any pain . Simetimes you can hit a nerve or vein but it ' s rare . if you do hot something just change direction slightly and its fine . The hardest part for me is waiting for the estrogen to finish injecting as it ' s very thick and can take a while with thinner needles . I use a larger needle to draw out of the vial and change to a smaller one to inject I hope this helps some .
