Since couple of years I'm facing intermittent issue when I wake up in morning I'm not able to get out of bed, my muscles on hand and legs are fatigue and no power to lift myself up. I'm using orthopedic mattress and with any solid object support like stool, table I'm able to pull myself up, this happens mostly on the morning and goes away in 20 to 30 min. this issue is on off. currently due to baby is small we're sleeping on the ground without bed and only mattress and it's very hard to get up, until i get stool support I'm not able to get up/walk ankle muscles are also fatigue which makes it hard to walk and if I go in speed my ankle might trust in opposite direction, similarly cannot lift any heavy object, but this is only 20 30 min issue then all is normal. let me know in your diagnosis and which doctor to consult.
