3. Tendinitis and bursitis Many tendons around the hip connect the muscles to the joint. These tendons can easily become inflamed if you overuse them or participate in strenuous activities. One of the most common causes of tendinitis at the hip joint, especially in runners, is iliotibial band syndrome — the iliotibial band is the thick span of tissue that runs from the outer rim of your pelvis to the outside of your knee. 
Im a skateboarder and a couple weeks ago i skated alot every day and my lefy hip was starting to get sore. But of course i couldnt resist skating so i kept skating and it got worse and worse to the point i couldnt really skate at all without my hip hurting but of course i would still mess around on the board doing tiny tricks but a couple days ago i was just skating around not really doing tricks and i slipped and kicked my leg out and REALLY hurt my hip and thought i tore a tendon or something and couldnt walk for two days, but its gotten alot better and i can walk fairly normal and i ice it everyday but whenever i stretch it its just a really sharp pain it doesnt feel like im stretching it. What do i do when all the stretch does is make a sharp pain? How do i strengthen my hip? And how long would it take to strengthen my hip to full strength again? Because i cant stand not being able to skate. Please reply so i can skate as soon as possible thank you

Some of these red flags are much less red than others, especially depending on the circumstances. For instance, “weight loss” is common and often the sign of successful diet! (Well, at least temporarily successful, anyway. 😃) Obviously, if you know of a harmless reason why you have a red flag symptom, it isn’t really a red flag (duh!). But every single actual red flag — in combination with severe low back pain that’s been going on for several weeks — is definitely a good reason to get yourself checked out.
