What is your vitamin B12 result?
Hello,
I have been diagnosed with ALS. Tingling is not a sign or symptom of ALS. ALS only affects the motor neurons so there is no pain, no loss of senses, no other sensations. ALS symptoms are: a loss of movement and range, loss of muscle, and muscle twitching.
I am not a doctor but I would tell you, "Don't worry, its not ALS".
To me your symptoms look like a pinched nerve around the sacrum and lumbar spine. A kinesiologist would help you with that.
But, the worst case to leg tingling could be MS. Get an MRI on your brain to find out.
Good Luck to you.
