I don't think you have ALS. I've been reading about it over the past 5-6 months and have read about all kinds of neurological maladies. There are so many problems that can be linked to the nervous system it's unbelievable.
From what you are describing it sounds like some sort of spinal problem. Maybe compression, or siatica. You did say you have scoliosis, maybe that has something to do with it.
Most people that have ALS don't experience pain, some do but a very, very few. I think your age and gender is on your side also.
Go to the neurologist and he/she can do an EMG test that looks for muscle weakness and along with that they do a NCV test that tests your nerves to see how long it takes them to respond to a shocking sensation. Both of these tests are a breeze. The EMG uses needles like in accupuncture.
If they don't find anything on either of these test ask your neuro about seeing a back specialist.
Good luck to you,
