I am a 25 year old female. Some 5 days back i began having weakness in my lower limbs, which has aggravated since then. I find problem majorly in walking and maintaining balance while standing for a while.I am also experiencing drooling and twitching in my right eye for more than a week now. This is third such episode within within 2 years, and such episodes, as i observed are preceded by exertion of some sort. Three years back i had problem of double sightedness for two days (also preceded by overworking), though a proper diagnosis could never be made for all these problems, and eventually these subside on their own.
My doctor says weakness is more in the right limb, and some reflexes are brisk.There is a certain waddling gait, which grows worse as and when i walk more. However, the electrolyte tests and nerve conduction tests including RNS are all normal.
I have been pescribed pyridostigmine (60 mg) twice a days since yesterday, but any visible effect hasnt been seen. Any diagnosis, please ?
