I have had 2 epidurals for 2 children. I remember while getting both, I kept having severe pain in my left hip and knee. They said "Hmmm." and that was about it. Since then, I have had hip/lowerback problems, and I've always had knee problems.
Now, as for bruising, I had a decent size bruise (probably 4 inches across), but they only stuck me one time on both occasions. I would imagine, after being stuck so many times, that massive bruising would be "normal". However, I would definitely go see the doctor if other symptoms begin.
The numbness is normal. I couldn't feel parts of my thighs for almost a month. I could pinch my leg and feel nothing. I could walk, just not feel surface pain. My legs were very weak and shaky, but I had just given birth. I don't know which the symptom was associated with, childbirth or the epidural.
Anyway, Best of luck with your side effects. I hope you get to feeling better soon.
