I also dealt with comorbidities, so I know how tricky that kind of balancing act is. Major nerve damage from the spinal lesion left me paraplegic for over 9 months, and the two months after my surgery felt like a series of dominoes falling: prolonged ileus, catheter, UTIs, stomach intubation, IV feeding, steroid-induced diabetes, DVT from not being able to move my legs, severe weight loss (40 lb in a month and a bit), pneumonia, etc etc.
But with patience and persistence we got those under control one at a time, and now I'm on a much-reduced list of prescription meds and just routine monitoring, living an almost-normal life (something I barely dared to hope for back then).
You'll get there too, but expect some turbulence along the flight path.
Wow, with all you’ve gone through I feel like a wimp! I wish the best for you!
