Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I passed carefully through your question and would explain that your husband symptoms (blood in the stool, yellow eyes) are not related to the cervical radiculopathy, which is causing hand numbness. Coming to this point, I would recommend performing further tests to investigate for the possible causes underlying his situation: - A fibrogastroscopy for ulcer - An abdominal ultrasound - Complete blood count for anemia - Kidney and liver function tests. Regarding the broken blood vessels in his eye, it is important to closely monitor his blood pressure frequently during the day for possible arterial hypertension. Hope you will find this answer helpful! Wishing good health, Dr. Iliri
