1. The first aim of this study is to examine whether slow repetitive TMS (rTMS) applied to SII in patients with pain and chronic pancreatitis has an analgesic effect as measured by changes in the Visual Analogue Scale (VAS) for pain and a decrease in analgesic intake, as well as an overall improvement in quality of life. In addition, if this study finds a significant effect of rTMS on pain reduction, the duration of this effect will be further assessed. TMS will be applied at parameters of stimulation known to decrease excitability.
