Hi and welcome,
I would strongly suggest you see your doctor, i genuinely doubt it has anything to do with a neurological condition like MS, because you have developed these issues directly after a medical procedure and resulting staff infection, that's a very coincidental time frame that can't be overlooked but keep in mind you do have a few preexisting medical issues and they are more likely involved with what you've been experiencing since the opp, more likely than a completely different type of medical condition like MS would be....
The type 2 diabetes, waking up nauseated and a balloon feeling in your throat, high levels of fatigue, cognitive confusion, mental health issues, shakiness etc could be suggestive of something like sleep apnea, so please tell your doctor about everything that's going on and if he/she doesn't know enough to help, it would be worth considering getting the opinions from medical specialists familiar with the conditions you have been diagnosed with.
Hope that helps.......JJ
If you think you might have MS have your PCP give you a neurological exam. If it is normal you do not have to worry about MS. It is checking reflexes and such. It is as accurate as a MRI. If it is abnormal you get a referral to a neurologist and they possibly do a MRI. It could be that you have several overlapping conditions with different symptoms.MS symptoms overlap with symptoms of many conditions. MS usually starts in the eyes.
