Maybe it's coincidence but my brother started having back pain over the weekend. since then I have as well (live in a different state) I have encountered 6 other people since then that are experiencing the same thing starting around the same time.
Might be nothing but might be something. Just seems strange.
Any related Mosquito bites? I have a friend you started having some back pain after being bite by a Mosquito.
