Question: Hi, Dr. My PCP put me on 5,000 units of vitamin D a few months ago due to severe fatigue every day. For a few days I took 1000 units of vit. D at bedtime also. Then I was feeling quite a bit better. However, my dr. Said Not to do the extra 1,000 units that it was not a good idea, but he did not really say why. Can u explain to me why not pls since it makes me feel much better. My D used to be 24 when I took 1,000 morning, 1000 at night.
With the 5,000 units, it moved up finally to 30 on testing.

For my sister , age 71, she had a back surgery to open up the spine, 3 vertebrae were to tight. Surgery by a neurosurgeon at cedars Sinai. Then she went to rehab for a few weeks, she has had 2 bladder infections, treated with 2 antibiotics but they did not get better. She is now only on one oxycodone but very constipated. She will have a colonoscopy early January. What can she do to be less constipated. She does not like Ducolax, she took Miralax for 2 days. What would be good to do to go and be less constipated. Many Thanks.

Detailed Answer:
Welcome and thanks for your query.
Your symptoms were due to the Vitamin D deficiency and you feel better after its correction. As per the present knowledge a person requires 1,500 to 2,000 units of vitamin D per day . If you are not exposing yourself to a good amount of sunlight , it would be advisable to continue vitamin D supplements. There are preparations containing 50,000 units and if you take once a month of that, would be sufficient if you find it easier than taking tablets daily.
As for your sister an osmotic laxative like Movicol or Duphalac would be preferable.
Do get back to me if you have further questions.

I was released from the emergency room on Friday - unable to walk with shooting pains down the front of my calves - body will freeze in position and right arm will turn into a claw- I breathe and then I am able to walk. The longer the distance from car to back of dept. store all mobility stops. Blood pressure is irregular and increases with pain. Right outer leg is numb - excessive fatigue. Joint pain in ankles in am throbbing pain in arms this is intermittent. Memory is as if I no longer have a filter for my thoughts. Right leg spasmed for about 30 seconds for no reason. Have been having balance issues in the past and dizziness - walk to right of wall. Also within the last 2 weeks all is getting worse. When fatigued I walk as if I am 90 years old. I am a 48 female non-smoker. I have been to numerous doctors - all test come back normal and they comment this is interesting but have no idea what is wrong with me. I have constant pain in my hip region - very tight. At the emergency I had a CAT scan and full blood work all is normal. I had a shooting pain in the back under the left shoulder blade which caused blood pressure to elevate to 212/110 as the pain subsided so did the blood pressure. I check blood pressure daily usually around 132/78 or lower. If I am in pain the blood pressure goes up. Any suggestions?? Denise

My doctor thinks I have adrenal fatigue or insufficiency after coming off a week of Prednisone (which was for sinusitis that hadn t resolved after 4 courses of Augmentin.) Symptoms included aching glands around head and shoulders, lightheadedness, dizziness, insomnia, terrible fatigue, strange aches here and there. I also have had cognitive issues - losing track of what I am talking about mid sentence. CT scan yesterday showed that the paranasal sinses are clear now and all blood tests, FBC, iron, thyroid etc were normal. My doctor has prescribed a lower dose of Prednisone for 3 weeks to kick start the Adrenal glands. Prior to my problem with sinusitis, I have had at least a year of stress due to grief, supporting others through grief, daughter getting married, changes at work and a greatly increased workload where I don t have time for leisure. I am 49 and mother to 3. I work full time.I have started the low dose prednisone but am worried that it will cause more problems. Should I stay on it?
