A diagnosis of MS cannot be made on symptoms alone. Many other conditions as well as medications, vitamin/mineral deficiencies and mental health problems, can cause similar symptoms as those seen in MS. MS is a diagnosis of exclusion, meaning all other possible causes for a person's symptoms must be ruled out, this is part of the diagnostic criteria (The Revised McDonald Criteria) for Multiple Sclerosis.
The criteria relies heavily on MRI evidence, if you are concerned about MS then a brain MRI is reasonable. Your low Vitamin D could cause your symptoms so it is a good idea to bring your D level back into a normal range either with a prescription D or over-the-counter D supplement. Repeat blood work is needed to check on the progress of increasing D levels, usually every 6 months to a year.
Medications and/or Psychotherapy to control your anxiety. Anxiety can cause physical symptoms which might be similar to symptoms seen in MS. If the anxiety is controlled it is possible for symptoms to improve or completely go away.
