I'm abit unsure of how you have greased it, I assume you have took the piston out, if you have then I don't know but if you haven't.. take the hose out the lever, poke a 5mm Allen key through and push so it pushes the piston out, then grease directly onto the seals and clean the bore inside, whack some 3 in 1 oil in there to give everything a thin lubing then reassemble and pump a few times to ensure its ok. I assume its bled with something else but blood as this happened to mine when I was stranded and bled mine with Strongbow. Good luck
