You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
Contact sports: It should go without saying; all contact sports should be firmly off your to-do list! That also includes sports than involve contact with another object like tennis or gold! Not only do these forms of exercise make you vulnerable to further injury, the rigorous movements required can place your hip joint under too much stress. Try and give the footie a miss for now and instead focus on other exercises you can do with your friends such as swimming or yoga!
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.
