足底筋膜炎是一种影响脚的疼痛状况，每走一步都能感受到。足底筋膜炎的主要症状是足弓疼痛。它通常位于您的脚底（鞋底），但疼痛可能被感知为散布在您的脚，脚踝和小腿的各个部位。因此，足底筋膜炎可能与影响足部的其他情况相混淆，反之亦然。有许多条件会导致足部疼痛并且可能被误认为是足底筋膜炎。在诊断足底筋膜炎时，通常需要评估和排除这些病症。足底筋膜破裂几乎总是比足底筋膜炎更痛。它通常还有前驱：足底筋膜炎或严重创伤。如果你患有足底筋膜炎，你就会冒着肌腱筋膜破裂的风险加剧和减弱。如果你的脚健康，那么它通常发生在创伤或对你的脚有重大影响。在足底筋膜炎中，足底筋膜在整个组织中具有微泪。由于足底筋膜破裂，这些眼泪更大并且发生了明显的损伤。这两种情况具有相似的症状，但它们的区别在于疼痛的严重程度和损伤的原因。足底筋膜的破裂通常伴有“砰砰声”。弹出的结果 – 足底筋膜破裂 – 是剧烈的疼痛，并且无法承受足部的重量。肿胀和瘀伤通常很快就会破裂。可能需要手术和其他医疗程序来帮助修复足底筋膜。关节炎是一个常见的问题，许多人患有身体某处。当关节炎发生在小腿，脚踝或足部的某些部位时，它可以散发出可以被感知的疼痛，就像感知足底筋膜炎的疼痛一样。当身体部位感冒时，关节炎通常会更加疼痛。早上的第一步可能是足底筋膜炎或足部关节炎的最痛苦的一天，仅仅因为解剖结构冷而紧张并且没有明显的预热。当脚变暖并且血液开始更加强劲地流动时，疼痛可能会消失。疼痛的定位不仅可能与足底筋膜炎疼痛相混淆，而且疼痛的发生也可能类似。当使用患有关节炎的关节时，关节炎疼痛通常更严重。当关节处于静止状态时，甚至可能不会出现疼痛，这与您在足底筋膜炎中看到的模式相同。所以你的脚后跟可能会有关节炎，直到你迈出一步并抓住鞋跟后才会注意到它。为了诊断足底筋膜炎，通常必须首先排除关节炎。关节炎可以通过医生进行更彻底的检查来诊断。也可能需要成像测试。
澳大利亚格里菲斯大学医学Assignment代写：足底筋膜炎
Plantar fasciitis is a painful condition affecting your foot and can be felt with every step you take. The main symptom of plantar fasciitis is a pain in the arch of your foot. It is usually localized at the bottom of your foot (the sole) but the pain may be perceived as radiating throughout parts of your foot, ankle, and lower leg. Because of this, plantar fasciitis may be confused with other conditions affecting your foot, or vice versa. There are a number of conditions that cause foot pain and can be mistaken for plantar fasciitis. These conditions typically need to be evaluated and ruled out when making a diagnosis of plantar fasciitis. A ruptured plantar fascia is almost always significantly more painful than plantar fasciitis. It also usually has a precursor: either plantar fasciitis or a significant trauma. If you suffer from plantar fasciitis, you do run the risk of it worsening and weakening to the point of your plantar fascia rupturing. If your foot is otherwise healthy, then it usually occurs during a trauma or significant impact to your foot. In plantar fasciitis, the plantar fascia has micro-tears throughout the tissue. With a ruptured plantar fascia, those tears are larger and a significant injury has occurred. The two conditions have similar symptoms but they are differentiated by the severity of pain and cause of the injury. The rupturing of your plantar fascia is usually accompanied by a “pop.” The result of that pop–the rupturing of the plantar fascia–is severe pain and an inability to bear weight on that foot. Swelling and bruising often soon follow the rupturing. Surgery and other medical procedures may be needed to help the mending of the plantar fascia. Arthritis is a common problem that many people suffer from somewhere in their body. When arthritis occurs in the lower leg, ankle, or some part of the foot, it can exude a pain that may be perceived in the same way that pain from plantar fasciitis is perceived. Arthritis can often be more painful when the body part is cold. The first step in the morning may be the most painful of the day with both plantar fasciitis or arthritis of the foot, simply because the anatomy is cold and tight and has not significantly warmed up. The pain may dissipate with both as the foot warms up and blood begins flowing more robustly. Not only may the localization of pain be confused with plantar fasciitis pain, but the occurrence of the pain can be similar. Arthritis pain is usually worse when the joint suffering from arthritis is being used. When the joint is at rest, then the pain may not even occur, which is the same pattern you see in plantar fasciitis. So you may have arthritis in your heel and not notice it until you take a step and engage the heel. To diagnose plantar fasciitis, arthritis must usually be ruled out first. Arthritis can be diagnosed with a more thorough workup by your doctor. Imaging tests may be needed as well.
