Throat problems

Hi everyone my name is Samantha and I am new to this site.  I hope this is in the right thread .

I have had problems with my throat since 1st June I am normally healthy but do suffer with being anaemic which i take iron spatone for been taking it since I was in my early twenties I am now 39 I take it every day and my iron cells are normal but at the bottom level and I suffer from constant throat clearing which started late teens and doctors said it was nervous and still have it now . 

Any way I was doing a 29 day course of yoga lessons as I was dealing with a lot of stress my uncle passed away and house problems and with covid etc and dealing with my kids and then on the 2nd June I noticed my right side of my neck very tight and hurting and my gland felt up so I went to doctors and a nurse practitioner looked at it and said it felt tense but my temp was ok etc so she did a blood test and my results came back fine only my white cells up a bit . And the next days it got worse it feels like very tight pressure inside the throat pushing into my food pipe then it relax on that side and goes to the other side and round the back of my neck I spoke to my dentist and she thought it could be a tooth infection as my tongue is swollen too I was on antibiotics from her and made no difference went to see her she looked at my tongue and looked at the wisdom teeth and said it was fine and was not teeth related and then I developed temp for one day and shakes and then my hands cold and feet cold then next day i went back to doctors who still couldnt guess what it could be so more antibiotics and still no difference and then I had a pressure under my chin like someone choking me so off to shrop doc and he said come off antibiotics as your blood test says you havent got an infection he looked inside mouth glands not up so he gave me antihistamines in case it was from something took them no better so back to the doctors as I have no appetite at all for food and I was a big eater and havent eaten right for the pass 6 days and the doctor looked inside my mouth again and said it could be a virus but my hubby or kids havent got it and because I have a yellow coating on tongue he thinks maybe oral thursh so at the moment on drops that I have to put on tongue he said rest and eat healthy but i cant really eat as I got no appetite and if I force myself to eat then I feel sick and inside my neck feels tight i have been burping as well and my glands feel tender and all doctors have said is that its aniexty but it isnt anyone else got this feeling . Under chin tightness and inside neck tightness and round back of head I also had temple pain etc any help would be great thank you as worried now been like this for 3 weeks Monday
