I had a neuro consultation when i was 12, and they doubted
myasthenia gravis, but all those tests were -ve. Now i am 18, and last year, i had was on high dose of steroids and antibiotics for months due to acute pneumonia, and my symptomps seems to have aggravated after the steroids were completely tapered.
Now i consulted a neuro again, and he doubted congenital myasthenia, congenital myopathy, mitochondrial cytopathy and steroid induced myopathy. He couldn't reach a diagnosis.
