Sounds like she has a rib out.
I’ve had that happen. Same feeling.
See a chiropractor.
Prayers done for Your Wife.
I will second the Chiropractor suggestion. I have been getting Chiropractic care for decades and it works. Sprained neck in 5th grade, fixed in about 2 weeks.
Around ‘92 work injury Lumbar and Thoracic Spine, drugs were useless went to the Chiropractor and was taken care of in a few weeks. The workers comp insurance company sent Me to a Neurologist (looked like freaking Doogie Howser md) and he wanted to fuze C4-6 and could only say that it was a 50/50 chance that would fix the problem. I told him (can’t post or I’ll get Banned.) NO FING WAY !!!
Take Your Wife to a Chiropractor !!!
