Hello Momma2boys and welcome to the forums.
First I would l like to say all human beings go through anxiety and your not an exception. Some may have more severe anxiety than others and most of the time, they have reasons to be. It is a normal human emotional experience so don't be too hard on yourself.
When it interferes with a person's life such as work, health or social interactions with others is when that person is encouraged to seek help in order to obtain effective coping mechanisms to reduce their anxiety level. (at least to their best ability). Sometimes psychotherapy and pharmacological means are used to help.
I can understand your concern and believe your concerns are valid.
Here is the HEALTH PAGES of MULTIPLE SCLEROSIS which is very resourceful:
http://www.medhelp.org/tags/show/7687/Multiple-Sclerosis?section=health_pages
Normally, Multiple Sclerosis is a diagnosis of exclusion, meaning that your doctor (PCP) and Neurologist will investigate other means of why you are experiencing the symptoms you have. There are simple things like Vitamin B12/Pernicious Anemia that can be corrected that can give you symptoms as you describe. I do not know what laboratory tests you have had so far, but most include: Thyroid Panel, Lipid Panel (cholesterol), Vitamin B12 and Folate, CRP, ESR (Erythrocyte Sedimentation Rate), Lyme, RPR (Syphillis), ANA with reflex if positive (Antinuclear Antibody - testing for autoimmune disorders), Rheumatoid Arthritis Factor, ACE (Angiotensin Converting Enzyme - for Sarcoidosis), Anti-dsDNA, Anticardiolipin IgG/IgM, CBC (Complete Blood Count), CMP (Complete Metabolic Panel - electrolytes/kidney function/liver enzymes) Celiac Disease Comprehensive, etc.
As you can see there is a lot of blood work that is usually done when someone like yourself experiences unexplained neurological symptoms. In addition to the laboratory tests, you may also be ordered to have a MRI of your brain and spine. MRI is superior to CT scans.
You also may have tests such as EMG (Electromyogram) a nerve conduction study and VEP (Visual Evoked Potential Test).
A lumbar puncture may also be considered where the doctor/Neurologist obtains a small amount of cerebrospinal fluid for microscopic examination to rule out infectious causes or to use as an aid to diagnose certain diseases such as MS -- although 10% of people who have MS will test negative for this (they look for 0-bands).
Try taking a glance at the Health Pages and you will find it is a great resource!
Again, welcome to the forums and I hope I was of some help.
Please let us know how you're doing!
