Hi - I'm a 38 year old mum to one. About 6 weeks ago I started taking thyroid medication due to high TSH. I had awful niggling headaches for a few weeks and then thankfully they stopped. But I started itching horrendously. It started in my hands, but would move to scalp or back. Always one area at a time. And I am running hot - not temperature, just feel like I am. no night sweats, just running warm throughout. 

The dr told me to come off the thyroid pills and I started taking an antihistamine which has really helped. But it's still happening. And now I have a painful neck and, I think, a swollen lymph below my right ear (which also feels full and odd).

I'm so scared I have cancer. I had full bloods done just before starting the thyroid pills and nothing else was amiss, and I've just had another set done to test for antibodies in addition. I also had my flu jab which I wonder whether could have triggered the lymph swelling.

But all I can think is cancer, despite wanting to remind myself that this all kicked off within weeks of me starting thyroid medication.

I wondered if anyone else has similar experience to this. Or alternatively could just tell me to calm the **** down .

Thanks in advance
