Bescarti, I have battled a some of these symptoms over the years having Irritable Bowel Syndrome. Covid made that worse, but, it has calmed down after 8 months. With Irritable Bowel you can have bloating, gas, fatigue, diarrhea or constipation, belly distension, spasmatic pain in one or both of your sides and tenderness on each side. It may be worth asking your Gastro doctor about. Praying for you!
