I had a nasty fall but am not bruising? WTF?

Yesterday afternoon I managed to really hurt myself by falling down part of the stairs after I stopped and bent down to pick up a cup. I started to slip, but then my legs were way up in the air. I've had a muscle spasm before where my legs came up to waist level then I hit the ground on my back. It happened again. I hit my spine/bottom of my right shoulder blade, then bounced in a seated position on my hip bones/sacrum down the last 4 steps, hitting the edge of each step--thankfully they are carpeted. 

I already have degenerative arthritis and broke my sacrum completely off as a teen when I fell off my horse onto a tree stump. I didn't get treatment because my pediatrician couldn't believe that my back could be that injured if I was able to walk around. I just have an extremely high pain tolerance. 

The xrays look fine, but I'm not bruised at all!!! I can barely move because of the trauma. The areas where I hit are obvious because they're hot and swollen, but not discolored. Dh looked at my back tonight, and he said that right on my spine where I hit the hardest, he can see dark purple mottling under the skin, really deep, and he thinks I'll be really bruised tomorrow. 

I try to look up not bruising on the internet, but there's nothing. All the articles talk about excess bruising. 

I've always been an excess bruiser. My inlaws have seen me pop my knuckle because the joints in my hands can hurt, then the whole area turns purple before their eyes. I've walked around with finger marks on my arms from "foreplay" with dh, but with the way I bruise, it looks like dh has hurt me. 

I'm going to call my general physician tomorrow and make an appointment to see him. I already have some blood work that he has ordered for me that I hadn't done yet because I had a flare of acute pancreatitis right before dh and I went to my inlaws for Christmas. 

We just got back into town Monday morning at 2am. I slept on Tues and went to dh's pain doctor on Wed. I was so excited to call my mom on Thurs afternoon because dh's doctor prescribed a new migraine medication and was sending dh to a special urologist who was going to take over dh's treatment for low testosterone. The pain doctor didn't realize that even with treatment for the past 3 years, dh's testosterone levels were still almost non existent. 

I am not taking any NSAIDS or aspirin (I got bleeding ulcers before) nor am I on any blood thinners. (I have a genetic mutation and can't keep a therapeutic level--I'm usually too high 6-9, yes 9) I tried Xaralto instead of Coumadin/Warfarin, but I felt like someone was beating my abdomen--my muscles would get all tense and sore like I had been beaten. I was in so much pain I couldn't move, so I stopped taking it. 

My vitamin D level has been low. My gp was going to put me back on prescription vitamin D but wanted to check my levels first. 

I didn't like my hematologist, so I'm looking for another one. I've just never heard of not bruising, and figured that there would be a pea that knew about this weird condition. I'm not using the peas for diagnoses, but info I've learned from the peas has been very useful in the past when trying to figure out how to treat some of my issues.
