Welcome to ThisIsMS, Dea7.
#1 Take a deep breath. I have no medical background; but, in my opinion, I think it is unlikely that you have ALS. Your symptoms are common to many conditions. The diagnosis of MS can only be made after other more likely possibilities have been ruled out.
#2 Prepare for your Monday appointment with your doctor by writing down a list of your symptoms – make each description as brief as possible. Take this paper with you to the appointment.
#3 With your doctor, outline the game plan for the investigation of your symptoms. Numbness/tingling/pain in the legs and arms/hands is the textbook definition of "peripheral neuropathy." This is a common symptom in many conditions. In investigating the cause of peripheral neuropathy, the University of Chicago suggests the following (Your doctor's game plan may be similar.):http://peripheralneuropathycenter.uchic ... #bloodtest
Blood tests are commonly employed to check for vitamin deficiencies, toxic elements and evidence of an abnormal immune response.
Depending on your individual situation, your doctor may request certain laboratory tests to identify potentially treatable causes for neuropathy. These include tests for:
Vitamin B12 and folate levels
Thyroid, liver and kidney functions
Oral glucose tolerance test
Antibodies to nerve components (e.g., anti-MAG antibody)
Antibodies related to celiac disease
Hepatitis C and B
(By the way, vitamin B12 deficiency can run in families. The "serum B12" blood test alone is not enough to rule out this possibility. Initial testing should also include a homocysteine test and a methylmalonic acid test.)
