<s>[INST] A friend of mine has developed no feeling in her one hand and it extends up her arm to near the elbow. It looks like some blood is pooling along the thumb. She has cancer in her abdomen and will be starting treatment again tomorrow. The ends of the other fingers on her right hand are just starting to do the same thing. [/INST] Hello, Thank you for your contact to health care magic. I understand your concern. If I am your doctor I suggest you it must be a metastasis to the finger that has caused a blood to store there. It is the malignant metastasis that has caused you such a symptoms.I will be happy to answer your further concernYou can contact me. Dr Arun Tank. Infectious disease specialist. Thank you. </s>
