So I'm not new to using NPP or this brand even/carrier oil, lately when I inject into my delts there is a visible lump(blood always comes out now)and painful as all hell for about 2 days. I'm using same syringes still going as deep as I have for last few years. I'm using same carrier oil with my testosterone so it shouldn't be that. Possibly not getting needle past scar tissue perhaps? I'm at a loss what else it could be. I'm leaner now than I ever have been and burying the needle as I always have. Just looking for ideas what it could be/if im on right track with thinking. There is no redness or swelling(i can massage the oil in)afterwards.
