I can't understand what's going on with my health?

I'm a 41 year old female that has always been healthy until about a year ago. I am overweight, but I don't drink or smoke and last year I started eating healthy and losing the excess weight..The problems started with sore throat that has never gone away, along with the sore throat I had an aching body (similar to light flu symptoms).I have been to the GP who has told me I have acid reflux but the medication I took made no difference whatsoever.Saw a consultant and did some test and discovered I had a small hernia and H.Pylori. I was given triple therapy(antibiotics) for the H.Pylori which I completed but the symptoms of a sore throat persist. When my sore throat feels really sore my ears get affected and I find my hearing muffled. Several times I have had the glands behind one of my ears swell up considerably for a few days at a time then they settle.Now I have started hearing clicking sounds from various parts of my body but for the past 10 ten days every time I walk I have an almost continuous clicking sound coming from my foot or knee (I am not sure which) which is so annoying. I have no swelling or direct pain but tenderness which could be what I have been mistaking for a sore body for the last few months.This afternoon the inside of my left arm is red and very hot to the touch. I know something is wrong but my previous GP has not diagnosed me so I have now just moved to a new GP after being with the previous GP for a year and a half and having no concrete diagnosis . On Monday I am seeing the Ear Nose and Throat specialist,and I want to request that my GP gets me to do a full and comprehensive blood test.I did a bone density scan a few months ago and I got the all clear, I did a full blood count beginning of last year and I got the all clear, so I have no idea what is going on with me healthwise. I know my immune system is compromised as I have facial warts (not very visible unless you look closely, if anything they look like tiny pimples) and that is a sign of an immune system that is weak otherwise the body would have fought off the herpes virus (which is what facial warts is). What can I do to get to the bottom of this? GP's seem to be clueless and in the year that I have had the symptoms, I keep getting additional symptoms that do not go away, I am really worried as I have always been healthy with only very minor issues that I managed to cure very fast. Any insights would be helpful.
