cramps如何理解？

Symptoms can be intermittent or constant and often appear weeks to months following DVT, but can occur up to years later. Symptoms are generally progressive over time and include pain in the extremity, heaviness of effected limb, itching, cramps, and paresthesia. Physical signs include edema of extremity, changes in skin pigmentation, venous dilation, telangiectasia, and ulceration

症状是间歇性或持续性的，通常在DVT后几周到几个月出现，但也可以在几年后出现。症状通常会随着时间的推移而进展，包括患肢疼痛、沉重、瘙痒、束缚感和感觉异常。体征包括四肢水肿、皮肤色素沉着改变、静脉扩张、毛细血管扩张和溃疡。（图E1）

老师，血栓后综合征 cramps是束缚感吗？
