My 77 year old husband had a stroke in 2006. His left carotid artery is completely blocked. He has remained with severe pain and numbness in his right foot and ankle. It has been hard for him to walk since then but has become increasingly worse as he's aged. His neurologist has sent him for many tests but they come back negative for the cause of his pain. Does anyone know of someone who has or is experiencing this? I was reading up on the thalamus and how it can play a big roll in this type of pain. Has anyone taken a thalamus product and has it helped? Thank you.
