sit well?啥意思？

A 67-year-old man with newly diagnosed colorectal cancer presents to the preoperative anesthesia assessment clinic for evaluation 1 day prior to a scheduled low anterior resection. He has worked as a farmer in a rural community with limited medical care. A diagnosis of type 2 diabetes was made 10 years ago, but he states he does not regularly check his glucose levels and he has not taken the prescribed medicine because it did not "sit well" with him. Besides feeling unsettled by the cancer diagnosis, his primary complaint is a painfully numb, pins-and-needles sensation in both feet that has become progressively worse over the past 2 years. After taking his medical history and performing a physical examination, you determine that he has painful diabetic neuropathy.

1例67岁男性新诊断为结直肠癌，在计划的低位前切除术前1天到术前麻醉评估诊所进行评价。他曾在医疗有限的农村社区做过农民。10年前诊断为2型糖尿病，但他说他没有定期检查血糖水平，也没有服用处方药，因为它没有和他“坐好”。除了对癌症诊断感到不安外，他的主要主诉是双足疼痛性麻木、针刺感，在过去2年中逐渐恶化。在采集他的病史并进行体格检查后，您确定他患有疼痛性糖尿病神经病变。
