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.
A pinched nerve in the hip or back can cause radiating lower back and hip pain. If you wonder what does nerve pain feel like – it often involves severe pain and numbness that may be referred from other areas of the body. For example, a pinched nerve in the upper back can cause numbness in the fingers. But if you're suffering with a pinched nerve—your main questions are probably ones of how to fix a pinched nerve, how long does a pinched nerve last, and how do you get pinched nerve relief? Often, pinched nerves are due to inflammation due to muscle tears, injuries, or pulled muscles. Sometimes, scar tissue from old injuries begins to accumulate and press on nerves. The best treatment for pinched nerves is often rest. But medications such as glucocorticoid injections and oral NSAIDs may help. For patients whose radicular pain has not improved with conservative treatment over six weeks and who want nonsurgical treatment, epidural injection of glucocorticoids may be reasonable.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
