Red Hot Ear....melancholy..thyroid problems? 28yoFemale

I have this persistent red hot ear that heats up at inopportune times.  Doctors tell me they "don't know" and I'm certainly not imagining this.  It will turn almost a purplish blue and there is a noticeably hot sensation to the ear surround.  People around me notice it as well.  I've had maybe 30 episodes within the past 5 years. Someone once told me that perhaps its a latex allergy but I have done everything to avoid latex and it still happens.

Here's my stats:
Happily married for 3 years.
28 year old female
5'3
125 lbs.
no children

I struggle with body fat that accumulates around my abdomen and I don't think it is normal.  I am always tired ----lethargic, yet I try to exercise and jog with my dog maybe 4 times a week for 30 min or more each time.

I sleep 8 hours a night.

I feel like my life is passing me by and I am in a dreamstate of sorts.  Would this be considered a "brain fog"?  I'm happy but well aware that 99% of circumstances surrounding me are beyond my control; that makes me pretty sad. I am NOT normal for myself right now.  I used to be the most happiest ENERGETIC person and that person is a distant memory.  I feel like I'm entrapped in a person's body that isn't me.  

I have history of ovarian cysts and have had surgery to correct such.
I'm not taking any birth control and haven't been for 5 years.
I take percocet when my pain is too intense (in connection with ovary problems)
I consume maybe 24 percocets per YEAR.

I don't drink alcohol.

Since last year I have struggled with SEVERE leg pain in my lower left leg that cannot be overcome by any pain medication.  I stretch I exercise nothing and eventually I will fall asleep out of exhaustion but in the midst of pain.  I have had this pop up roughly 5 times.

I am hypoglycemic.
I eat a lot of junk food.  In fact, I CANNOT live without sugar. thoughts of sugary foods consume my day and I cannot think if I don't have some form of sugar.  I've tried to go on a sugarless diet but my blood pressure dives and I nearly pass out.  

but i drink 8 or more glasses of water per day.
I have a history of anemia as a child.

I had a tooth pulled a few months back and leading up to it my heart was hurting; the dentist told me I have anxiety and it made me think: do i have anxiety? I don't think so but I'm not sure.  I seem pretty normal.

and I have had a history of chronic laryngitis as I am a professional singer. my dr. has always put me on the z pack.

i greatly appreciate your insight into whether any of these symptoms are related or not and/or what you can recommend is wrong with me.
