So, went to see my GP this morning. Had him check for inner ear infection - no sign of one. Had a pregnancy test (a few people have mentioned it could be that) but thankfully that was negative. As much as if love children one day, it won't be anytime soon and I'm not in a proper relationship and the person I sleep with doesn't want children. Showed him the rash on my knee, he said unlikely to be a heat rash as it would have gone down by now, and when I was talking to him/ showing the rash he suggested he wanted more blood test to check how my blood is clotting, may be something to do with that.. I asked him to double check my last blood results and he told me my iron was a little high, but nothing major, suggested that is down to the b12 injections and that something to do with my liver was different but again, nothing to worry about. Got to go for bloods late next week as the nurse I want to see is fully booked and then off half of next week. Then to see the GP again a week later with the results. Xx
