Good evening Dr. Grief;\I am a 61 year old, white, female. I have a history of back pain due to degenerative disc disease. I ve had two major surgeries, one in the cervical spine and one in the lumbar area. I also have a cyst in the T8/T9 area that should not be, but is, symptomatic. I m on a pain med treatment, closely followed by my pain specialist. Lately, about 4 weeks now, I guess, I have been experiencing debilitating fatigue along with sleepiness that just knocks me on my but. I get light headed, nauseated, and cannot function normally. For instance, just today I got up at six, got my husband off to work, took a shower, got my grandchild ready, and got ready to go to a doctor appt. with my pain management doctor. I suddenly felt light headed and so tired that I had to lay down. I made sure my granddaughter (who is home from school with a broken leg) was safe with me on my bed and fell asleep and could not manage to get up until 1:30. even then, it was hard to get up and go about my business. I rescheduled my appt. and didn t dare to try driving. I have had some very close calls while driving, nearly wrecking several times. Try as I might, I cannot stay awake when this happens. My meds haven t changed in about a year, so I don t think my meds has anything to do with it. I plan to make an appointment with my family doctor tomorrow.
