Thankyou for responding.I went to an ENT at the very beginning when I could not swallow and months later when I had lost a ton of weight.He was actually taken back when he saw all the weight I had lost.At the beginning I had some acid reflux,but he did not know what was causing it.My diet was good and he did not think that had anything to do with it.We ran more swallowing tests and they could not find a thing.Trouble swallowing,a stiff neck,and weakness in the trunk of my body were some of my first symptoms.I had hair loss too.My weakness got to the point where I could not hold my purse or lift a window.The problem is I thought it was from a horrible reaction to the iron infusion,but I just kept on getting worse with many more symptoms.My one doctor even checked for lead poisoning possibly from the iron infusion.I really just think covid is involved because no one can figure it out and my tests are all coming back fine.Right before my iron infusion I went to the Beach.Even though I got the vaccine the Beach was the first time I let my guard down by not wearing a mask.I bet I picked it up there.It feels like not one part of my body is functioning properly and I am slowly dying.I walked 8 miles a day and was very healthy besides the years of heavy periods causing anemia before this came on.I just keep praying I find someone with something similar or maybe knows someone that is in the same situation.The only people I have seen that have some similar symptoms that are not showing on conventional tests have had long covid.It is like covid hides.
