If any of the above sound familiar, then chances are that you could be suffering from an autoimmune disease which is why you need to seek out immediate medical attention.

One of the reasons for you to experience sharp and constant pain in your lower limb could be as a result of an autoimmune condition. This is why your doctor, after first assessing your current condition would order for a CT scan of the limb in question as this would provide him with a more comprehensive image of the limb in question. You are required to inform your doctor regarding your current state of health as well as any medication that you may be taking since this may have a bearing as physicians are less likely to suggest a CT scan especially if you are pregnant. The CT scan itself should take only an hour or less, you may be required to abstain from medication for a few hours prior to the test but other than this, you do not have to undergo any additional preparations.

The CT scan provides a detailed image of the organ or bone in question, and even images blood vessels accurately. This is why doctors often prefer CT scan as an imaging tool over others as it enables them to diagnose the condition accurately.

The lab technician may require you to ingest a liquid which would contain a contrasting dye, this is supposed to help build a more detailed picture of your body. He would ask you to disrobe, change into a hospital gown, and lie on the table. The CT scan machine would then develop a series of slices of the limb in question from various angles so as to provide your doctor with an in-depth detailed image. These images should be available in a few hours after which your doctor would evaluate the same to determine the causative factors. Once he has diagnosed your current condition, he may order follow up tests to confirm the same, especially in case of an auto-immune condition; this should enable him to prescribe an effective treatment for your current condition.
