2 years back i did squats of 25 repitions 2 sets . i came home was feeling week in legs.went out and fell a few times. i was like having no strength in my knees i was hospitalized my potassium level was slightly low i was given drip. i was prescribed an calcim and vitamin capsule. but i still feel weakness in my legs if i exert them they kind of become wobbly and no strength even to sit on a couch and get up easily .
