Hi there. It is very reasuring that your MRI and nerve conduction tests came back normal. Unfortunately, this does not rule out "cramp fasciculation syndrome" or "benign fasciculation syndrome." These things normally do not show up on either MRI or nerve conduction/EMG tests. So both pieces of advice you received might be right. The good news is that if you have one of these syndromes they are not life or limb threatening and often improve over time with improvements in one's psychosocial situation. On the other hand, there might also be a low grade, ongoing autoimmune or autoinflammatory condition resulting in these symptoms (and not a primary neurological condition). I would suggest you have your CRP and ESR tested first. These are both blood tests that look for evidence of overactivity of the immune system. If elevated, I would suggest you ask your doctor for a referral to a rheumatologist. These are the doctors that specialize in autoimmune and autoinflammatory conditions. If the levels are not elevated, I would see a mental health professional to see if you can get any underlying stress or anxiety disorders under control. This might result in dramatic improvement of your symptoms.
