莫顿神经瘤
概述
莫顿神经瘤是一种会引起足底疼痛的疾病，最常见于第三和第四脚趾之间的部位。莫顿神经瘤可能会感觉像鞋子里有小石子，或者袜子褶皱硌脚一样。莫顿神经瘤涉及通向脚趾的神经周围组织增厚。这会导致足底尖锐的灼痛。你可能会感到受累脚趾有刺痛、灼烧感或麻木。高跟鞋或紧身鞋与莫顿神经瘤的发生有关。许多人通过换穿低跟鞋和鞋头较宽的鞋子来缓解症状。有时可能需要皮质类固醇注射或手术治疗。
症状
通常，这种病症没有任何外部迹象，例如肿块。相反，您可能会出现以下症状：感觉就像鞋子里有一颗小石子 脚掌前部灼痛，可能放射到脚趾 脚趾发麻或刺痛 除了这些症状外，您可能会发现脱掉鞋子并揉搓脚部通常有助于缓解疼痛。最好不要忽视任何持续几天以上的脚痛。如果您脚掌前部的灼痛没有改善，即使更换了鞋履并改变了可能导致脚部受压的活动，也应去看医生。
何时去看医生
最好不要忽视任何持续几天以上的脚痛。如果您脚掌部位有灼痛感，并且即使更换鞋履和改变可能导致脚部受压的活动后仍未改善，请去看医生。
病因
莫顿神经瘤似乎是由于通向脚趾的神经之一受到刺激、压迫或损伤而引起的。
风险因素
Morton's neuroma is a painful condition affecting the ball of the foot. Several things seem to make it more likely to happen.
Tight or Ill-Fitting Shoes: Shoes that are too tight or have high heels put extra pressure on the ball of your foot and toes. This constant pressure can irritate the nerve that runs between the toes, leading to the painful Morton's neuroma. Poorly fitting shoes, even if they aren't high heels, can cause the same issue.
Repetitive Impact: Activities that involve a lot of running or jumping, like jogging and some types of dancing, can repeatedly stress the ball of your foot. This repetitive impact can also irritate the nerve and cause Morton's neuroma. Sports like rock climbing or snow skiing, which often require tight-fitting shoes, can also put the feet under a lot of strain.
Foot Structure: Some people are more prone to Morton's neuroma because of the shape of their feet. Conditions like bunions (a bump on the joint of the big toe), hammertoes (curving toes), high arches, or flat feet can change the way weight is distributed across the foot. This uneven distribution can put extra pressure on the nerve between the toes, increasing the risk of developing Morton's neuroma.
