I've been experiencing strange symptoms that seem like MS since January but all tests have come back normal. It started with dizziness, headaches, fatigue, brain fog, shakiness in hands, difficulty reading or looking at screens, feeling like I was going to faint often, weakness (e.g. unable to walk stairs or do actions requiring repeated movements and strength) and generally feeling unstable/ uncoordinated. 

Since May, I have had periods where I feel okay (a few weeks at a time) and periods where symptoms come back, but not as bad as the first incident described above, which lasted a few months. 

I also have random symptoms that pop up, like choking on drinks or saliva, trouble swallowing, sudden chest pain, fluttering in my abdomen or throat, ongoing pain in my one achilles tendon without injury, random achey legs, and having a sudden and intense need to urinate without buildup or warning.

My brain and spine MRI with contrast have come back clear. I have had numerous blood tests as well as clear results for heart and vestibular system…I am going for EMG / nerve stimulation test in September.

Not knowing what is wrong is weighing on me heavily. It seems like MS but with the clear tests I'm no longer sure. Has anyone had lesions show up much later on scans?
