My calves often swell when I am sitting for more than 3 hours in a driving or an airplane seat position. Despite keeping my salt intake low, it still happens, how can I treat/prevent this other than keeping my legs higher than my heart? THANKS!

I've been off of it for over 5 years. I exercise every day, 5 mi. on the bike,I hit the weights and do calistenics. However, I can't lose the appitite that I never had while using.

I know what your thinking, junkie looser!! but people do change, in prison I found God, education ( I now have an engineering degree) and respect for my body.

Although I am built (6' 225lbs.) and can bench 300+ free weights (scarry uhn) , I still have belly fat. I tend a strict diet, low fat meats (chicken, turkey), fish, fruits and vegtables. I eat alot and am never full. prison food goes right through you if you know what I mean. I was wondering if there was a drug that would help me without any side effects such as sleeplessness and addiction or should I find a more strict set of exercises that curtail to weight loss.

Is it old age, I am 42?

I have this thick white vaginal discharge and it has been going on consistently for almost a year now. I have gone to the doctor about 2 or 3 times about this. I have had three pap smears and a biopsy done on me. You would think as common as these symtoms sound they would know. But all the tests done on me we're negative. They gave me presciption medicine and cream for a yeast infection. I took it and it didn't go away. Now a year ago I started having sex and about three months into that that's when the symtoms started showing. Doctors said it could be irritation to latex,So as bad as I didn't want to..my partner and I quit using condoms for a while and It didn't seem to solve the problem. And she had also said It could just be hormonal and that it would eventually go away. Now I figured that was probably what it was at first, but come on now.. it's been a little while over a year now. Can a something hormonal last this long!? what I would really like is a diagnosis and a treatment.

If you have surgery for a detached retina do you have to stay in the hospital or even go to the hospital? I think I may have one and I am absolutley terrified of hospitals and everything to do with them!!

This has really affected my self confidence.

Doctors have no compassion!!! Just take another pill. If you have Medicare or Medicade just let them die, so there is one less person the government has to pay thier expences!!!

He says he will give up Craigslist searching for drugs (he has done is steady for a month), he says he will give up Ritalin even though it was originally prescribed after a sleep study that determined he had a sleep disorder...because he abused, over-took, eventually snorted). Now he wants to hang onto ephedra. I just think we are prolonging my pain and his addiction. He has to mail order Ephedra, it is now illegal in the US as far as I know. His teeth are brown, his hair looks different, he is more mentally insecure than when he smoked coke. What do you all think. Besides that I am insane and sick.

One of my friends is anorexic (we are getting her help) but I have watched her and another friend-we will call him Bob- go at it lately. Well when the anorexic friend told us about her problems Bob went crazy and yelled at her.

Well she kept tell him to stop being so rude about it. He then said something like this (i wasnt there so i dont know word for word) "You hurting yourself hurts me- but if you want to kill yourself not eating, be my guest"

She was really upset and they didnt talk for a few days. Well now they are talking but everytime she brings up food or eating he changes the subject....

How do I make them friends again because she won't try to help herself if he isnt involved? HELP HELP!!!


sorry if thats confusing

I weigh 216lbs and I am trying to get to around 180lbs.
My workout consists of 30 min walk on treadmill, 15 min on bike and 15 min of stepper.
Would 3 times per week be enough? And is it true that I will not lose weight faster if I do it daily?

lately i have been having some cramps similar to period cramps and everything i eat turns into mush. My last period started Sep. 7th and lasted 5 days. I have also had some thick clear discharge which is normal i think during ovulation. I havent had sex in about 2 weeks. My husband and i also use condoms and we check them afterward to make sure its not leaking. We are just not ready to start a family, but if we do then we do.

My question is, are we pretty much in the clear with not getting pregnant and that the pains could just being something else like a cyst or me starting to work out alot.

Hey
I don't really know what to do with myself. I'm 25, intelligent (MA English) healthy, got a nice long term boy who loves me, pretty, average weight, fairly nice upbringing. Great lifestyle, great job.
BUT
I've always hated the way I look. I've been dieting since age 10 because my mother was obsessed about her weight too. I started 3 day fasts at 12years old. I started self harming at 9-10years old for attention, I think. The self harm stopped (cutting anyway) with my boyfriends help 4years ago.
I've pulled my hair out since I was 11years old..not to so bad that Im balding, but it's apretty bad tick. Not always pulling but touching my head all the time especially when Im bored or unoccupied/nervous.
My lifestyle is very very active, 3-4hours exercise a day and usually very healthy, but still trying to lose weight all the time. Sometimes 3days fasting, sometimes very low calorie days, sometimes eating too large(but healthy)meal and purging.
Im a nightmare! Help.
