Hello,
Muscle disorders are primarily of 2 types, one is a degenerative type of condition called muscular dystrophies and the other is inflammatory called myositis.
From what you are describing, it seems like the former.
The way to confirm this is by a physical examination to see the power of muscles and any associated condition like sensory involvement.
And by tests like muscle enzymes called CPK, aldolase, LDH.
The other is a muscle biopsy and an EMG.
In addition, MRI of the involved muscles can be helpful.
The treatment largely depends on the etiology of the problem.
Sometimes hypothyroididm, osteomalacia and other endocrine problems can produce similar clinical features.

yes right,
I meant that any kind of muscle dystrophy or endocrine causes like hypothyroidism and osteomalacia should be ruled out first.
these should be first done by doing muscle enzymes and later by others like EMG and biopsies.

hello,
Most of the secondary causes like endocrine disorders and inflammatory myositis are curable.
However the muscular dystrophies are slowly progressive problems, and dont really have a complete cure. But some of the mild conditions may only require exercises to keep them under control.
