I don’t drink, smoke/vape, or take any recreational drugs. I’ve never had a serious injury, I can remember plenty of times slightly tweaking my back or shoulder while exercising. I’ve worked out for many years but when this started the fatigue and muscle weakness didn’t allow me to keep working out. I can think of plenty of occasions I might’ve hit my head on something but not severe enough to seek medical attention at the time. Could it be related? Possibly, it’s hard to think of every time something like that could’ve happened. Every blood test is in the normal range besides the few I mentioned which didn’t seem to a be a cause of concern. I haven’t seen a cardiologist but I’ve seen pulmonary and lungs/breathing were fine. Also, a chest X-ray was done which came back normal. My diet is well balanced, I include protein, carbs, fats, fruits, and vegetables. No issues there as I’ve been monitoring what I eat as well. Last year when this occurred I did lose some weight about 15-20 pounds, I gradually gained that weight back over the past year. I am a man so I don’t deal with any menstrual related issues. My iron levels were normal as well too. God bless you too, I’ll continue to pray. Happy Easter.
