My son recently told me feels heaviness in the right side of his body. He is 7 years old. He said he has always felt this way ever since he can remember. He is currently being treated for convergence insufficiency, a neurological eye condition in which his eyes don't team together well. He also was found by his eye doctor to have retained 6 out of 7 of the primitive reflexes. He is currently undergoing therapy for his eye condition and therapy which will help with the reflex integration. I'm not sure if this is a separate condition or something that relates to his eye conditon. Any infomation would be appreciated.
