I wanted to say hello and also to ask for some advice 

I visited my Dr 6 weeks ago due to ongoing problems with a hoarse voice . I have not had a cold , no temperature or mucus . 
I was diagnosed 3 years ago with a multi modular goiter on my thyroid. At almost 51 I'm at a time in my life where everything hormone wise is up on the air , so new aches and pains, so so tired but not getting a decent sleep had become the norm for me . 
I had been putting off a Drs visit due to Covid but as voice had worsened over a couple of Months I made an appointment . He listened to me, examined me, Sent off bloods and said he would refer me to ENT.

one week later I get an NHS text at 10.10pm saying that as I had been referred for suspected head and neck cancer I needed an ultrasound which in a few weeks would be followed by an endoscopy.

i had the ultrasound 3 weeks ago , have heard nothing . Symptoms are far worse voice now all

but disappears after a few sentences, I struggle to breath, my neck is huge , lymph nodes up in neck under armpits and behind ears hurts and I feel rotten. The most worrying part is I now have a dull ache in my upper right arm and pain in right side of neck and shoulder , it's there all the time  . So called my Drs again last week, had a  difficult chat because of voice and he said I should have been seen within 2 weeks as an urgent referral ( now 6 weeks have passed )

I am worried my husband is really worrying and feels that I need to go to A&E to try and get seen because my neck is obviously being restricted in some way

i don't like to waste anyone's time and I understand that there will be unavoidable delays due to Covid but I can't go to work as I'm unable to speak and I feel worse each day ( still no temperature and have had a clear Covid test as my husband is a teacher so all household had to have one so he could return to work.

what shall I do ? ( sorry for the very long post )
