How long does a sciatica last?
Sciatica lasts from a few days to a few weeks. In the majority of cases, it will go away by itself, as it has came: the problem that triggered it must be solved: in the case of a herniated disc, for example, the herniated disc must stop putting pressure on the nerve.
Sciatica lasts longer or will not go away if one doesn’t adapt their behavior, so as not to perform the actions or action that trigger it.
If we don’t pay attention to the way we bend down, to the physical efforts we make in everyday life, to the number of hours that we sit on a day, we postpone the healing and the longer the sciatica lasts, the harder it is to go away.
If the situation doesn’t improve after 3 months and / or sciatica is too painful and prevents normal life and activities, surgery may be considered.
