There is a possible complicated physiological explanation for why that happens.
A rather simplistic explanation is that our brain gets confusing information from our muscles because on the one hand it has to fire more to get it moving (which makes us think that something is heavy) and on the other hand the tone of the muscle spindle is decreased (which makes us think that something is light).
I know that in the early days of my illness I would have no idea if the cup I tried to pick up was heavy or light. ..................

I thought all the posts on this thread were rather interesting.
I personally remembered that a cup of coffee
felt like it was a heavy object when holding it in my hands a couple of years ago. But the posts made me think about how it was in more detail.
The
first few seconds of holding a cup it felt like its normal weight (of pre myasthenia times)
But by
6 seconds, holding that same cup of coffee now felt like holding the weight of a bucket of concrete -
away from the body.
That was quite a stable pattern for many months with diurnal fluctuations, which to me at that time just meant my coffee would turn into concrete much faster by the end of the day!!!
These days I donīt notice the weight of the coffee anymore but I
do notice the weight of my own arms changing from day to day when engaged in an activity above my head. So some days they feel 10 times as heavy as other days - but that I can actually
do tasks with arms at a 90+ degree angle away from the body makes me an extremely grateful person
I know Iīm not the only one to experience this, but it got me thinking about describing the sensation of weight and also about speed, it takes a longer time to reach those old myasthenic thresholds these days and my symptoms are milder yet fluctuating faster than they did previously (at least where the deltoids are concerned.....)
