Hi claudedaniel and welcome to NeuroTalk
Have you had a MRI of your spine? If not, it might be something to ask for just in case your symptoms are related to some sort of back issue. Just a note about Multiple Sclerosis (MS): MS is a disease of the Central Nervous System(CNS) and can affect the spinal cord which can cause symptoms similar to those you list.
It's difficult to say what may be causing your symptoms, there are many conditions/illnesses which can cause the symptoms you are describing.
