Bobby,
Did you change anything in your apartment -- different sheets, a rug, soap, . .
Could you perhaps be allergic to a food that you added back into your food plan recently?


Is it pain in the lower back? I could be the bike. The bike apparently
has to be the right fit for the rider. Can it be adjusted?
Also, bike riding puts a lot of strain on the back.

This is what I found when I went looking:
The Core / abdomen muscles need to be strong for bike riding.

A lot of people miss their core entirely during training.
That’s a big problem because as a cyclist, you use your core muscles to generate power and control the movement of your bicycle,” says Silvis.
“When your core is relatively weak, you’ll get fatigue and back strain
and pain much sooner than someone who is better conditioned in their lumbar spine area.”

The difference between the riders: The riders with pain had less-developed transverse abdominals and lumbar multifidus spinae, so they had less lower back endurance.
Fast fix: [U]Perform core exercises that target your inner unit.
