Hello, found out that my thyroid has gone loopy 3months ago. Have been on 100mg of thyroxine for the last 4weeks and am still felling like cr*p. I just wanted to know if anyone else had experinced panic attack and wierd anxiety problems after starting the meds. Also in the mornings my arms and legs feel really weak and heavy. All this seems to have started since I started the thyroxine. It's just been a nightmare I had a really normal easy pregnancy and delivery and first six months with my fantastic DS. Life just recently has become unbearable, I don't feel like I am ever going to get better. I can get any sense out of the GP and the endo is so aloof and uninterested in any side effects I may be having. I have also lost shedloads of weight which is not normal for an underactive thyroid although it was overactive for a bit I think before it went underactive. I just want to know that this is going to improve as at the moment it feels like a never ending nightmare. Sorry such a moany message. Would love to hear any other experiences. Thankyou
