<s>[INST] I have really bad chest pain. Cresendo type pain. Had double CABG 2 years ago but this pain has started about 9 months ago. Comes every couple of months and getting worse. Surgeon said maybe coronary spasms see cardiologist about getting more meds. I also have tingling and numbness in fingers on both hands left arm tingling sometimes. Been to ER several times with this and they never can find nothing wrong. Heart cath July was fine. When I have these I noticed drinking water will take pain away as well as Nitro. I wished I had never had bypass. It is not my stomach or in my mind. Looks like many people according to some of the blogs are having this. What has this surgeon done to me I cannot look to a future of this. Any ideas on what this could be. [/INST] Numbness in hands and fingers has many causes , you rolled out any cardiac cause by doing a cath. and it was fine , so let's check out another causes :1- Diabetic Neuropathy : a change in one's nerves ( especially peripheral nerves ) due to high glucose level for a long time , so you should check your blood sugar .2- other causes of neuropathies : which can affect the nerves like viral infections or exposure to a cold weather with w fine clothes .3- Renauld's Disease : a disease in which a spasm in the peripheral circulation due to exposure to a very cold weather .* you may need to visit a neurologist after rolling out the diabetic cause , and you may recieve a fine doses of vitamin B12 and alpha lipoic acid . </s>
