Good Evening, Hope To Find You Well. I'm A 57

Good evening, hope to find you well. I'm a 57 year old female behaving like a teenager my son says:) I slipped at school (two months ago) and came down hard on "all fours" hands and knees. My left hand took a very hard impact turning outwards. So did my right knee, sharp pain. I had to go on teaching so I limped to class, climbing stairs a few times and got on with life. Right, I hear you say, now why are you complaining of pain then? Long story short: my left wrist has a painful swelling, hurting in the fleshy part of my hand under the thumb as well. I need only twist it sharply to the left absentmindedly to climb through the roof! So I bind it up when I sleep. Right knee, stff swollen whenever I climb stairs or twist it in the wrong direction. Oh and I walked into the
marble table now there's a bruise as big as a tennis ball with a sore lump as big as acorn in the middle. Other than that I'm fine:) should I see a doctor? Xxx
