<s>[INST] When I get up too fast and start walking I get leg tremors and feint feeling. I am diabetic type 2, had bypass 3 surgery 13 years ago. I am on meds for feet pain at night (amytriptyline). I have not discussed with my doctor yet but will soon on my next appointment. When I have these episodes, I stop and take deep breaths and in a short time I am o.k. [/INST] Hello. I have been through your question and understand your concern. Your symptoms seem to be related to orthostatic hypotension, which is a benign condition, caused by venous insufficiency. Uncontrolled diabetes can cause this by affecting vast asylum which are the vessels which supply the big vessels. Arteries and veins beside carrying blood, are also structures which need to be supplied by blood in order to stay healthy, which are carried out by this tiny vessels called vast asylum. Diabetes affects this tiny vessels causing sometimes orthostatic hypotension. So I recommend an endocrinological consult to check your glucose blood level and the located hemoglobin level. Hope this helps, please feel free using MHC for further questions </s>
