Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.
Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is. However I will try to provide you with some useful information.
You have many symptoms, and they would be difficult to all tie together. The back pain with radiation to the arm and chest could be musculoskeletal or due to a pinched nerve (what is termed a radiculopathy).
The muscle twitches, or fasiculations, could be due to what is called benign fasciculation syndrome, which I will abbreviate as BFS, a condition in which there are involuntary twitches of various muscle groups, most commonly the legs but also the face, arms, eyes, and tongue. If the diagnosis is confirmed and other causes are excluded, it can be safely said that the likelihood of progression or occurrence of a serious neurologic condition is low.
However in general (and please understand I am not trying to imply I feel this is the case in you), when fasciculations occur in the setting of a specific associated symptoms, disorders such as ALS (also called Lou Gherig's disease), a condition called spinal muscular atrophy, polio-like viruses, west nile virus, and other infections could be a possibility. Another nervous system problem, neuropathy, may also lead to fasciculations. There will again be associated weakness or sensory changes.
It must be emphasized that in the majority of cases muscle twitches are BENIGN meaning that they are of no consequence and are not resulting from a serious cause. In such cases, the twitches may be related to anxiety/stress, caffeine, and often occur after recent strenuous activity or muscle over-use. It is important in such cases to reduce stress/anxiety levels and to reduce caffeine intake.
I suggest follow up with your primary doctor and you may benefit from evaluation by a neurologist as your primary doctor feels fit. It is important that you discuss your concerns with him/her. If there is concern for a neurologic disorder leading to the twitches, evaluation with a study called EMG/NCS which evaluations how nerves conduct electricity and how muscles respond may be indicated.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
twitching is a concern for many. mine is due to spine problems, nerves ect. i even have them all over. strong ones in my arms hands. i have lost muscle tissue in my wrists and hands due to c6-8 facet joints and radiculopathy. get a referral from your pc to a nuerologist. god bless, cher
