So 3 days ago I was walking down the hardwood stairs and I had socks on which I normally do but I wasn’t holding the railing because my hands were full so I slipped and fell down the stairs straight on my butt.. two weeks ago I went to doctor for sciatica and turns up I have herniated disc and arthritis in my L5 (I think) and I have numbness and tingling down leg which it finally felt 100% and then this happened and now I’m in worse pain than before.. I can’t really walk, run, sit, lay, or touch my butt or lower back.. the bruise is HARD and really warm after 3 days.. someone tell me if I should go to a patient first or doctor about this.. the color keeps changing every few hours. The top one is now bottom was 2 hours ago
