Barbara O’Brien gives a good summary of the three types of dukkha we humans experience:

The Buddha taught there are three main categories of dukkha. These are:

1. Suffering or pain (dukkha-dukkha)
2. Impermanence or change (viparinama-dukkha)
3. Conditioned states (samkhara-dukkha)

Suffering or Pain (Dukkha-dukkha). Ordinary suffering, as defined by the English word, is one form of dukkha. This includes physical, emotional and mental pain.

Impermanence or Change (Viparinama-dukkha). Anything that is not permanent, that is subject to change, is dukkha. Thus, happiness is dukkha, because it is not permanent. Great success, which fades with the passing of time, is dukkha. Even the purest state of bliss experienced in spiritual practice is dukkha. This doesn’t mean that happiness, success and bliss are bad, or that it’s wrong to enjoy them. If you feel happy, then enjoy feeling happy. Just don’t cling to it.

Conditioned States (Samkhara-dukkha). To be conditioned is to be dependent on or affected by something else. According to the teaching of dependent origination, all phenomena are conditioned. Everything affects everything else. This is the most difficult part of the teachings on dukkha to understand, but it is critical to understanding Buddhism.
