Hello there,
You are not alone. I have HbSS and I experience every symptom you mentioned. My advice to you is that anytime you feel tingling in your feet, try to step/walk around on your tippy toes for about 2mins. You'll immediately notice that the tingling sensation will disappear. As far as fatigue, try to work in intervals i.e. work on something for 20mins then take a 7min break and organize your day in intervals. That way, you're not exhausting yourself because you've scheduled periods of rest. As for joint pain, go on YouTube and start with beginner's yoga every other day or twice a week. I promise you, the joint pain won't be as intense. I hope these recommendations help.
