I suffered with excruciating headaches during very early recovery last summer.The headaches started up around 2 weeks in,then lasted for a further 2weeks.I can liken them to having my head in a vice.And as one grew in intensity,my thoughts and emotions and feelings of anxiety plus utter panic would also intensify.At the onset of the heafaches I was terrified as I didn't realize that this was my brain healing.The support and knowledge from everyone on SR was amazing.Such a relief too.Hang pn in there,your headaches will subside
