I want to share this story in case other people experience or have experienced something similar. I've never heard of a fatigue exacerbation, but I may have had one.
Background: My fatigue became so bad in June that I just wanted to die. I wasn't suicidal (takes too much energy), but I was hoping and praying that I would just die. Just not wake up. I couldn't stand the thought of living out my life in such a miserable state.
I cancelled a cancer-screening colonoscopy (the one you get as a prize for turning 50) because I hoped that I did have cancer and would not treat it then could die. That's when something woke up in me, and I asked my husband to get me to a doctor to get this depression under control and to see if there was a non-MS reason for my fatigue.
He went with me to see my primary care physician (PCP), and I'm now on depression medication which made me more tired at first, but I didn't mind so much. I think I'll be on this med for a long time because I'm enjoying birdwatching again. And I don't want to die anymore. Success there.
To make a long story short: In the last three months, I saw three doctors; had numerous and extensive blood tests and urine cultures; had four ultrasounds, one mammogram, one colonoscopy; and underwent a thyroid-nodule biopsy. All the lumps, cysts, and nodules are benign. I'm now on prescription-strength Vitamin D and a thyroid pill to suppress the growth of the thyroid nodule (no, the thyroid was NOT the cause of the fatigue), as well as the anti-depressant.
I have to conclude that the almost three-month severe fatigue episode was caused by the MS after all.
I want to thank everyone who's been keeping an eye on me and keeping my spirits up these last two months. I couldn't have gotten through this hell without you. If you see someone who is in crisis, don't hesitate to check on them. It will be appreciated.
