Thyroid Test

I have felt awful (lightheaded, dizzy, extremely sleepy, constipated) for the last 6 weeks.  Test came back normal but I still feel like it might be my thyroid.

TSH was 2.2 (normal range according to lab is .35 - 3.74)
T4 Free was .9 (normal range according to lab is .76 - 1.46)

Any ideas?  All blood work came back fine too (B12, folate).

Thanks!!!

Thanks for all the info.  I go back to the doctor in a few days to get results of my MRI and to discuss the next plan of action.  The only thing that I changed a month before this happened was my birth control.  I went from taking the mini pill to a combo pill.  I took two months of the combo pill and switched back to the mini pill.  I have been back on the mini pill for 3 weeks now.  I wonder if this could be a side effect I am experiencing?

The excerpt doesn't look that small really :)

A acute (sudden), intense attack of vertigo is a listed symptom of MS especially at the onset of the disease.  Constipation and fatigue are also symptoms of MS. This is just one possibility. I came across the article "Dizziness and Vertigo" from the Mutiple Sclerosis Resource Centre website and this is a small excerpt from the article....

"What is dizziness and vertigo?

These are both common symptoms of MS. The two terms imply that they are one and the same; however they each apply to two specific types of symptom.

Vertigo is referred to as a severe sensation of the person, or room and surroundings spinning. Acute vertigo i.e. sudden onset of continuous vertigo is often quite severe and alarming to the person with MS. The illusion of motion is very powerful and unnerving and can sometimes lead to nausea and vomiting.

It is often made worse by inclining the head a particular way or by lying down. Also when the other senses such as sight are unable to be used, for example, in a darkened room, it often aggravates things and makes vertigo much worse. The sensation is similar to acute sea-sickness or having drunk much too much alcohol.

Although acute vertigo can be distressing, it usually recedes over time, typically a few weeks, although it can be as long as several months before it passes entirely and there may be left a residual tendency towards further, if less severe, episodes and is usually accompanied by partial or complete loss of balance which is aggravated by fast turning movements.

Vertigo is associated with several other conditions apart from MS, some of these are conditions are associated with dysfunction of the vestibular nerve and others are conditions of the balance organs in the inner ear, therefore people often undergo investigations by an Ear, Nose and Throat Consultant to determine whether it is in fact an inner ear problem or a demyelination problem."

Yes, it came on suddenly and severe.  So it may not be hypothyroidism but I'm so miserable I'm looking at every possibility.   No other symptoms.  Thanks!

You suddenly felt awful 6 weeks ago? Generally speaking, hypothyroidism  develops slowly and can take years.  That said your free T4 is on the lower side. Any other symptoms?
