Abdominal aneurysm is uncommon in your age group and does not give fluttering/twitching or muscle spasm as symptoms. The muscle contractions/spasm you feel in all likelihood is muscle fasciculation or muscle twitch. Twitching is caused by minor muscle contractions in one particular area, or the persistent and uncontrolled twitching of a muscle group in a distribution of a single nerve fiber or filament. Usually they are benign and resolve on their own, but persistent flutter may need following investigations;1) electromyography (EMG)2) nerve conduction velocity (NCV)3) blood electrolytes like calcium, magnesium, potassium, sodium, etc4) thyroid and parathyroid function tests5) blood chemistry and complete metabolic profileThe common causes can be;1) Idiopathic; no cause is ascertained and majority falls in this group.2) Increased caffeine intake3) Increased alcohol intake4) Medications5) Deficiency in diet and nutrients / minerals6) Some neurological diseases; uncommonPlease feel free for your follow up questions.Dr. Arun
You are very welcome.
Yes. Muscle twitch can last for more than 24 hours and many times may continue for 2-3 days. In your case there are two point specific which need address;
1) Is it abdominal aortic aneurysm? The answer is big No.
2) Does this symptoms warrant any emergency measure or point to anything serious? The answer is again No.
I can understand this is annoying as this is a persistent nagging sensation. But in all likelihood this will resolve on it's own. Anxiety, tiredness, stress, electrolytes imbalance, dehydration all can be responsible for the persistence of the twitching.
It is pleasure and privilege assisting you.
You are most welcome.
Wish you a very happy and prosperous new year.
