Even the Mona Lisa is Falling Apart....

I think I need one of those throat scope things done.  I gotten this pain off and on for at least a year now that feels like a piece of glass is stuck in my throat/chest.  I think it's usually worse when I swallow pills or eat something chocolaty, but I'm not sure.  Tonight it's been terrible.  It started around noon and hasn't let up.  I put up with it through water aerobics and now I'm just annoyed.  I'm making some ginger pu-erh to see if that helps.  Ginger is supposed to be good for your gut.  I've probably got a tear or ulcer or something from taking so many OTC pain pills.  I've been trying to avoid those recently and am sticking to the muscle relaxers the doctor gave me.
I also had this rumbling that started around the same time as the esophagus pain.  It got worse after water aerobics and I had to lie down.  Eventually I got diarrhea.  It started out mostly solid and has gradually lessened in frequency and is completely liquid now.  At least I feel a bit better now.
Oh, and my knee hurts.  When I walk it feels like it needs to pop.  I get that feeling in my hips sometimes, but they usually pop immediately.  It hurts like hell for a second and then feels better.  My knee isn't doing that though.  It's the stupid knee I hurt in middle school playing softball.  The doctor then said there was fluid on it that couldn't be drained and it would give me fits when I was older.  I'm sure he didn't mean at the age of 29, but he probably wasn't assuming I'd be a gelatinous blob.
How is it I don't have cankles yet?
