Muscle weakness or fatigue?
by jymm, Jul 25, 2003 12:00AM
How does true muscle weakness, due to muscle disease, not lack of use, differ from muscle fatigue? Specifically, the fatigue experienced in Parkinson's disease? I have Parkinson's (rt. side) and for several years I have felt a distinct weakness in my right arm, shoulder, wrist,etc. I have slowly been able to do less of those things that I used to do with ease. i.e. lifting, carrying, gripping, etc. I get occasional weakness in my quadricepts at the point where they attach to my knee. It is occsional there, but the rt. arm has had a steady, slow progression of weakness. How does the clinical presentation differ between muscle fatigue and muscle weakness?

Muscle weakness is generally present immediately upon using the muscle, while muscle fatigue develops with continued activity. Both refer to weakness of the muslces, but differ in how quickly the weakness becomes evident. If you have not discussed these symptoms with your Neurologist I would. He/she can examine you and make sure no other problem is occurring.
if other symptoms i would research AGHD- adult growth hormone deficiency or see if GH injections would help your muscles.
they sure helped me-- i now have strength in my muscles-- something i have never had.
also look into magnesium deficiency-- and read about it-- it may help?
I am a 25 year old hispanic female. I have very mild CAH (congenital adrenal hyperplasia), and I take 2.5 mg of prednisone daily. Last year, I was on an Isoniazid treatment of 9 months due to a positive skin ppd (tuberculosis).
For years I have been experiencing dizziness and faintness and drops in blood pressure, but recently, along with my usual dizziness and weakness I have been experiencing a heavyness in my arms and legs, a weakness I can't seem to explain. It is almost as if when I lay down or sit down, my legs feeled nailed to the bed or the floor. Its like I have to think about moving them, since they feel so heavy. I've recently also been having back pain. It started with my lower back and I though I was sleeping wrong, etc., but after almost a month, this pain has spread throughout my back. It almost feels like flu pain, when your muscles ache. I am starting to get a bit concerned because these episodes are becoming more frequent, usually they would be months apart, but last Tuesday I got this way and yesterday (almost a week later) I got it again. This last one has even lasted longer...I still feel a bit weak in my arms and legs.
My paternal grandfather had Multiple Sclerosis and I wondering it I could be developing this.
Please let me know if there are any suggestions as to what I should do.
thank you.
