In our research study, we asked about access to pain relief, because that is something we would like to know about. Not only are menstruators missing school, work and exercise because of a lack of access; this could also be because of lack of access to pain relief.
After a couple of years of doing this work, we got a request for some pain relief, so we send up hot water bottles and heating pads. Microwaveable beanbags are often a bit too heavy.
