My back :(

[Lindsey]

For being 23 years old and already having this many back problems, I don't even want to think of how I'll feel at 50, 60, or 70
2 years ago I worked in the lab at the company where I currently work. I was on construction sites all day, hauling around heavy testing equipment, 5 gallon pails of wet concrete, pails of asphalt, etc. and my back was always in pain. Then last year, I was DROPPED on the pavement in the winter, and landed on my tailbone and shoulders. My back hurt for weeks but I didn't go to a doctor. Later on in the year, out of nowhere, the pain came back right in my lower back and sometimes it was so bad I couldn't walk. I went to the doctor and she got me to get x-rays right away. Ater 4 x-rays I waited for a week and heard nothing. I called the doctor's office and they told me "If we haven't called you, there was probably nothing wrong." and eventually the pain went away.
Last night I was walking around grocery shopping, getting ready for a big camping trip this weekend, when I felt something in my lower back go funny. It felt almost numb for a bit but by the time I got home it was hurting. I could still move so it wasn't a big deal. I slept well and this morning I was moving around in bed with no problem, I completely forgot about my back. As soon as I tried to sit up I started bawling. It hurts SO bad. I can stand up straight or lay down. Any pressure on my lower back at all basically makes me burst out in tears. I'm going to the doctor this morning instead of going to work.
I really don't want to ruin everyone's camping trip They won't go without me because I'm the one person everyone knows.
