I Have "currently" Been Ill Since Christmas. However, It's Been

I have "currently" been ill since Christmas. However, it's been forever since I've felt "ok". This round started with sinus infection that became bronchitis that morphed into pneumonia. Nothing doctor has tried is working. Here is a list of "Current" symptoms:

Non productive cough
Literally BONE tired…not really tired but truly exhausted
     When working come home and literally cannot move (sit on edge of bed to change)
     Wednesday, was “up & out” for short trip to store (2 hours) and went home and crashed
Sleep
     Trouble sleeping but even when I do, wake up feeling just as tired or worse than before I slept
          Never feel truly refreshed
Joint/Muscle pain
     Constant Charlie Horses, muscle pain (calves, arms, bum), ankles (especially left..swollen with pain)
     Fluid retention
Headaches
Lymph nodes ~ Neck still painful (Feel as though there are pebbles in my neck)
Sore Throat ~ Comes and goes, voice comes and goes
Difficulty concentrating
     Short & long term memory
     Often feel as though I’m in a fog
Lightheaded
     Sometimes it’s worse with position change (blood pressure low?)
Sensory
     Smell ~ Odors really bother me (i.e. earrings), cooking raw meat,
     Vision ~ clouded at times, noticing changes in vision
     Touch ~ foot pain )like pins and needles)
Circulation ~ Left hand (couldn’t get ring off), Left ankle ~ Fluid retention
Heartburn ~ really bad especially when drinking water (i know sounds strange)
Night Chills/Sweats ~ Usually cool but been sleeping without covers with fan on Freeing my hubby out
Bowel issues ~ One extreme to the other

Any clue
