Hi and welcome,
All over random muscle twitching are not typically a sign of there being serious or chronic neurological conditions like MS or ALS, the most common causes are vitamin deficiencies ie magnesium, low vit B, low vit D etc, low potassium, calcium deficiency etc, hormonal imbalances, mental health issues ie general anxiety, health anxiety, work and life stresses etc, medications side effects, low or high thyroid hormone levels, electrolyte imbalance, too much caffeine, overexertion, dehydration, lack of sleep or sleep quality etc often though non-medical changes are typically enough to combat frequent muscle twitching, so looking into anything in your life that you can change or improve on is usually the recommended first step.
If you were experiencing isolated or more specific muscle twitching along with additional pain, weakness, loss of sensation, pins and needles or tingling, muscle atrophy, changes in vision or hearing, loss of balance, difficulty speaking or swallowing etc then i would of been recommending you get a referral to a neurologist for a clinical neurological assessment and have the basic tests run eg MRI brain and spine, EMG etc but because you are 'not' experiencing any of these types of additional issues to be suggestive or consistent with a serious or chronic disease happening i honestly believe your anxiety over twitching is leading you off track and is causing you to start worrying unnecessarily about conditions that all over random muscle twitching doesn't truly match....
I hope this helps......JJ
Oh and I take a statin med for high cholesterol. I’m 30 female but overweight. I quit my atorvaststin for about 4 months to see if symptoms would improve and they didn’t. So I assumed the twitching wasn’t from the med. I had to get back on the med.
I forgot to mention that all my blood work that was last checked was normal. So I’m not deficient in anything. I also try to drink a lot of water.
