My forehead hit a tree trunk while out walking and I fell down and rolled into the street!

Fortunately no cars were coming in the lane, and a gentlemen stopped and helped me up. I did not think I broke anything so I declined a ride somewhere and continued to walk down the street. If anything was to blame I was looking down as I walked down a sidewalk which I have traversed many tines, instead of straight ahead and had no idea a split trunk of a tree was leaning way out in the sidewalk. I hit it so hard I knew I could not stay on my feet even though I pedalled backwards desperately striving for balance. Nor after I started going down, could I keep from rolling off the sidewalk into the street! My purse went way out there. Let's see, I scraped my elbow, and stort of strained that one arm and shoulder which I used to break my fall. I thanked god I have been carrying so many packages for years on my walks that my arms were strong.
The city streets are hazardous, and you do have to keep your eyes peeled at all times for unexpected hazards like raised sidewalks! Oh and these brick roadways--before I got used to my walking path, I nearly fell down twice over the same raised brick. I am mighty careful now when I walk on cobbled streets and sidewalks. But I just did not expect that damned tree to be leaning way out in the pathway! I felt like calling the city and telling them to cut that hazard to walkers down, but doubted if anybody else was going to miss seeing it entirely, practically knocking themselves out.
I decided not to tell Doc today that I fell down. We had been talking for weeks about my sister Linda's bad fall and hitting her head on the edge of a sidewalk, wondering if this might have pinched a nerve in her back and caused her hands to start going numb. And congratulating ourselves on our great nimbleness and ability to keep on our feet even when practically tottering. She still has not been able to get to a specialist and get her numb hands checked out She also says now she might have twinged her back swinging a pick to break up hard ground and put in a garden, but I tell you right now I don't do pick and shovel. But this fall has convincd me I had better quit carrying quite so many groceries at a time. And make more trips. Although I was carrying nothing to speak of when I fell.
I told my daughter when I happened to be talking to her, and she was alarmed, but she told me I was better off to keep walking anyway, than to quit, or my muscles would atrophy for sure. I know that. So I will try to look for big trees in my pathway. I have vowed I will rise my eyes from time to time to see what is up as well as what is down!
