Myself Dr Josh- and I’m happy to help with your question today.
I am sorry to hear about your problems.
Well, There are few causes for Fasciculations it doesn't mean there has to be some serious underlying problems.
Possible causes are-
-Thyroid gland dysfunction
-Electrolyte abnormalities( as it has come normal, so this possibility can be ruled out).
-Medication side effects
-Neuropathy (nerve diseases)
-Myopathy (muscle diseases)
-Pinched spinal nerves
-ALS (a type of motor neuron disorder)
-Excessive caffeine intake
I am not telling all these above are applicable in your case, but providing you with a list of possibilities based on what we see in our clinical practice.
As you see in the above list there are many non serious causes too for Fasciculations.
If this symptoms persists, or worsens, or any new symptoms appear then you need a thorough evaluation and examination in the clinic followed by certain relevant investigations like-
blood tests & an EMG/Nerve conduction test etc and they will help in ruling out conditions like thyroid disease, electrolyte disturbances, neuropathy, myopathy, ALS etc.
Also, stress could cause such symptoms. You may try stress-busters and see whether they help like meditation/yogas, counseling, hypnotherapy, acupuncture etc.
-You can Increase your fluid intake to at least 10 glasses of water daily.
-Increase the calcium in your diet. At your age, you need at least 1000mg of calcium daily.
-You can take Motrin 500mg if fasciculations is severe in nature.
-Take sips of cold water throughout the day.
Please see your primary doctor and get this issue clinically evaluated.
