The sciatic nerve is the largest and longest nerve in the body. It arises from the spinal cord as a collection of fibers from the lower vertebrae. This nerve is responsible for the sensation of the skin of the foot and entire lower leg except for a small area on the inner side. It also supplies muscles in the anterior, lateral and posterior compartments of the leg.
• Psoriatic arthritis. Psoriatic arthritis is a form of arthritis accompanied by the skin disease psoriasis. The skin disease often precedes the arthritis; in a small percentage the joint disease develops before the skin disease. For about 20 percent of people with psoriatic arthritis, the disease involves the spine. In some cases, bony overgrowth can cause two or more vertebrae to grow together, or fuse, causing stiffness.
Please note that none of the above given tips or recommendations substitute medical advice. Important: consult a health professional in case of an injury or if you suspect overuse of joints or a medical condition such as a fracture. A physician should be consulted in those acute cases when the condition is accompanied by reddening, swelling or hyperthermia of joints, ongoing joint trouble or severe pain and/or are associated with neurological symptoms
The hip rotators not only rotate the thigh on the pelvis but more functionally rotate the pelvis on the weight bearing fixed thigh. Activities such as swing a golf club, and even just walking require some rotation of the pelvis on the weight bearing leg. While we don't need that much range of motion to walk, activities such as running, dancing, tennis, and many other sports can require more hip rotation.
While you can’t choose where the weight comes off, you can eventually slim your hips so long as you stay consistent in your training. Cardiovascular exercise can help you lose some fat, but strength training serves a twofold purpose, burning fat while developing muscle for all-over tightening. “The more you build a muscle, the more [that part of the body] is going to firm up,” Braun says.
Of course, you know what it feels like to have a tight muscle. But tight hips aren't just uncomfortable—they can lead to all sorts of other aches and pains, especially in the lower back. "People focus on the hips and say their hips are tight, but we don't always think about the fact that the lower back connects to our legs at the hip," Charlee Atkins, C.S.C.S., instructor at Soul Annex in New York City and creator of Le Stretch class, tells SELF. Tight hip flexors make it harder for your pelvis to rotate properly, which can cause your lower back to overcompensate, "and this can be a setup for lower-back injury," Teo Mendez, M.D., an orthopedic surgeon at NY Orthopedics who focuses on operative and non-operative management of sports-related injuries, musculoskeletal injuries, and arthritis, tells SELF.
A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
