Anyone else had thyroid problems. Mine has been overactive before, during and after pregnancy on various occassions. The first time was 4 years ago and it was treated with tablets but recurred when i became pregnant and then went normal of its own accord only to become high again after i gave birth. it has been slowly going down without medication but my last blood test was totally different- showing underactive, high levels of tsh and low levels of t4. the specialist prescribed thyroxine but i asked for another blood test just to be sure. the results are not back yet. Just wondered if this was usual and if anyone else had experience. I have been all over the place recently. just moved house and started to feel mega depressed but at same time having anxiety/panic attacks and fluttering heart. i also have muscle cramps especially in lower legs. my heartbeat otherwise seems fairly normal. any ideas ladies?
