Patient discussion about source

Q. what are the sources for high density lipoprotein? I have heard that high density lipoprotein is good for heart. What differences does it make in heart’s health and what are the sources for high density lipoprotein?

A. Hi Liam, it is very important that we have high density lipoprotein (HDL) in our body. The fact is that the HDL is formed inside the body. They are known as good cholesterol as they are famous for their protection for heart against the heart diseases. It has been found that Vitamin B3 or Niacin consumption increases the count of HDL. It’s good to cut on the diet having more of saturated fats and oils, which increases the chances of heart attack.

Q. It’s actually a real source of irritation to me. I can't stand. Any such experiences…. The cesarean incision done on my body is really sensitive. I avoid touching it. I try to wear clothes that come up over my scar line, and I hate it when my son steps on the area when we're playing. It’s actually a real source of irritation to me. I can't stand. Any such experiences….

A. I don't think I had sensitivity like you. As far as I can remember I was able to wear jeans once it healed. One thing that does set off the sensitivity for me is when my brother`s dog of the right height jumps on me and puts their claws over the area. I wish to know is that area sensitive or paining? Both make a lot of difference. Better consult with your physician.

Q. Is there any good source for heel pain relief, besides NSAIDs? My heel pain is most severe at night when I sleep. It's as if the way I position my feet worsen the condition, but I'm at a loss to know how to position my feet. During the day my heels feel so but don't typically bother me.

A. I have found that keeping my feet flexed (the position they are in when standing) helps ease the pain of plantar facitis. I also don't let my feet get cold(wear socks)and keep heavy blankets and quilts off the feet. Placing a box under the covers at the foot of the bed will help keep the blankets up. Do try the exercises recommended on the above web sites. It usually resolves in about 6 months. Best wishes!
