10. Swelling
Swelling is not a problem caused by sciatica so much as a symptom that will commonly coincide with sciatica. That’s because sciatica is traditionally caused by pressure on the sciatic nerve, or by irritation to the same nerve. When you get swelling in the lower back region, whether this is due to a trauma, a broken bone, a sprained muscle, or anything else, this can then lead to that pressure.
Thus, it is very common to find that swelling occurs in conjunction with this pain and that you might experience both at the same time. If you notice this symptom, it’s not likely caused by sciatica but it does increase the likelihood that sciatica is responsible!
