Not dangerous: While you would not to have multiple ct scans performed daily, having necessary scans performed such as you are describing, pose relatively little risk. As with any medical test/procedure, the risk:benefit must be considered.
Dr. Bruce J. Stringer

Not an issue: There is no additional risk to have the 2 exams at the same time as opposed to waiting so random interval. Indeed, having both exams together might allow the two studies to be done with less overlap and reduce total dosage. If MRI were an alternative there would be no radiation exposure.

Does a lower back ache mean I am in labor?

No: It could especially if it is crampy and comes and goes every few minutes. However, it could be due to additional strain in your low back muscles due to your expanding belly and less postural support from your stomach (rectus) muscles. It could also be pain in your pelvis (si joints) from the hip bones "moving" to create more room for your baby to come out. If uncertain see your healthcare provider.

Possible: Back pain in pregnancy is extremely common. The added weight and the change in the curve of the spine both contribute to the back pain.

It should get better after the birth, but if it persists or gets worse, then you need to see a spine surgeon.

You have sciatica.: Sorry you are suffering from this...There are several common causes of sciatica including irritation of the spinal nerves from a herniated disk. If your pain does not get better, if numbness affects the crotch, or if you have bowel or bladder difficulty then you need a surgical evaluation, otherwise your primary care provider can take care of getting the sciatica to cool down.

Yes: I recomend you keep the throat clean. Rinse and swish after meals. Use an antiseptic mouth wash. Avoid feeding the invading organisms.
