Hurt knee - BAD

Well, I had my first REALLY BAD accident with the pole.  I SMASHED into the pole with my knee while going full force.  I fell to the ground and I couldn't even catch my breath for about 15 minutes because it hurt so much.  It took me almost 45 minutes before I could even get up.  I've been icing it all day.  Now it is 15 hours later, and if I don't move it, it isn't too bad but even the slightest bend will cause a horrible pain that has me in tears and it will last for 5 - 10 minutes.  I have an extremely high tolerance for pain so if I am saying it hurts, that is saying a LOT!!!   There is a pretty good size lump on my knee too.  Hubby wants me to go into the ER but I don't want to spend my day there, (besides, it costs and arm and a leg to go to the ER).  If it is still bad on Tuesday, I guess I'll go see my doctor.   I really hope I didn't mess up my knee too bad😕.  I want to get back on my pole!  (Although I am a little frightened to get back on)
