Why does it feel like warm water is running down my leg?

Below are some conditions that will explain why it feels like warm water is running down your leg, such as:


Radiculopathy (pinched nerve) is when nerves cease to properly work. Symptoms include; pain along the outer side of the thigh, numbness & weakness in the outer/inner thigh, and difficulty in controlling specific body muscles. Sometimes, sciatica will occur from a pinched nerve. When sciatica happens, a warm sensation in the leg may also occur.

Pinched nerves (sciatica) are due to an underlying condition. Therefore, there are many reasons it could exist. Such as:

Greater Trochanteric Pain Syndrome (GTPS)
