I am so very sorry you two are dealing with this especially @Puravidaville. If you have trouble finding a cause and or after ruling out any serious issues (aka doctors cant find ish) i highly recommend looking into mind body medicine.
Id recommend 2 books. "The Great Pain Deception " by Steve Ozanich and the Mind Body prescription by Dr John Sarno. These are all typical symptoms of Tension Myoneural Syndrome or mind body syndrome or tms equivalents.
I hope you two find answers soon. Blessings and Prayers 🙌🙏
