I tick all the boxes in the checklist, mum had a goitre and a growth on her thyroid non cancerous. My symptons are joint pains, pins and needles, cramps, anaemia some months, some months chronic fatigue, mental fog, depressive episodes, absolutely no drive whatsoever sometimes and self inflicted isolation, constipation, one left dry eye that sometimes weeps for days. I can cope with the physical symptons but the mental one's I find really hard, however one period cycle in every 3 or 4 kickstarts whatever it is that's faulty in me, I get up and am literally superwoman, I hit deadlines with my job, I'm organised, I've got the drive back to do the stuff that gets left when I'm low. This kicks in exactly 24hours before a period starts but like I said, its not every period. Gradually over the days that follow being supercharged I can feel the energy almost physically draining away and I start to slump again, struggling to function. I paid an online gp who suggested Hypothyroidism which after reading the definition symptons etc made perfect sense, its interesting to note also that my sisters share the same symptons including the leaky eye. My health authority goes on the TSH test and my results came back normal whatever normal means, I've read somewhere that TSH alone isn't a reliable indicator but don't know what else to do. Any suggestions?
