That being said, sometimes lymphedema can be diagnosed by comparing the affected limb to the opposite limb.

因此，有时可以通过比较患肢和对侧正常肢体来诊断淋巴水肿。

Treatment depends on how severe the edema is, and how far along the fibrosis is in the affected limb.

淋巴水肿的治疗取决于水肿的严重程度以及患肢的纤维化程度。

Finally, during stage three, lymphostatic elephantiasis, swelling becomes irreversible, and the affected limbs are really large and hardened from fibrosis.

最终，在第三期，即象皮病阶段，肿胀不可逆，患侧肢体由于纤维化而明显增大，皮肤非常坚硬甚至并发其他病变。
