Hi, !
First off, congratulations on your weight loss and your continuing efforts to get and stay as healthy as possible. Building your muscle strength is a GREAT way to protect your health!
With your medical complexities, I hesitate to offer any advice that may not be right for your situation. There's the obvious stuff, like staying hydrated during workouts. Have you tried electrolyte drinks, like Gatorade, or are those not an option due to your digestive issues? Keeping the right balance of hydration and electrolytes can help with muscle cramps and spasms following a workout, but, again, your situation is unique. Proper stretching after workouts can help, too, though I know you need to be careful to not overdo it and risk injury. Also, while soaking in a hot tub is not an option (and those public tubs can be kinda gross to begin with), can you soak your legs up to the knee? Is massage an option? Massage tools that can be purchased at, say Walmart or Amazon?
If you haven't done so already, I would definitely bring this up with your doctor and perhaps a PT with strong knowledge of a situation like yours. I think the textbook advice might not be overly helpful, but I could be wrong.
Again, kudos for working out and taking care of yourself and I hope your efforts continue to pay off and that you can get to the bottom of the muscle spasms and fatigue.
Best, Erin, Team Member.
