OK Martin. This sounds like a problem with your thoracic spine--probably a disk that's out of place and is compressing a nerve root.. The other possibility would be a vitamin B12 deficiency. The best thing for you to do is see a doctor about this and were I that doctor I'd get blood work and an MRI of your thoracid spine to see what the problem is exactly.
Let me know if you need any more information here
