Flare up from using a riding mower?

Today I rode our riding mower for 2.5 hours to mow our 3 acre property and shortly after getting done I felt like I got ran over by a dump truck. Everything hurts...everything. I suppose there is a lot of compression and release going on in the spine, especially on uneven ground, But its absolutely crazy that just riding the bumps and ups and downs of a riding mower could cause such a flare up, but it always does. It started as just my arm and neck muscles hurting from holding and turning the wheel but before long my entire body was on fire, and I literally feel like someone beat me with a baseball bat from head to toe. I swear I feel better pushing a regular mower, but to do so for 3 acres isn't practical. Anyone else experience the same problem?

Have to load up on pain pills to even sleep tonight

We have a large property and my husband has to mow a lot. I really want to help, but all that vibration concerns me. I've been having so much pain recently, I don't want to add to it.......so I'm not going to help mow.
It wouldn't surprise me in the least if all that vibration has affected you. Do you wear ear protectors? Is it a mower that has handles on each side or rather a steering wheel? Is the seat fairly comfortable? Maybe you hold yourself in a position that might contribute to the pain?
But my guess is that it's the vibration. Our nerves are just plain funky.

Could you consider hiring someone to mow the yard?

I hope you feel better soon!

We live on less than an acre and I can't ride the mower either. My 80 year old father has to do it! I feel so guilty letting him do it.
