<p>I need help. I went to the doctor this morning so they can take a blood sample. I think they took too much blood (3 bottles of them) on my left arm. Seven hours has passed and it still feels weak. My right arm is warm, while my left arm is cold because of lack of blood. How can I produce more blood in my body? It feels really weird!</p>
<p>It's normal to feel a little weird after having blood taken but you shouldn't be asking people on the cc boards for advice in this case. You should call your doctor!!</p>
<p>wow... lol... wrong place to ask... first off, i WOULD say run it under warm water, which promotes blood flow, and eat nutritious foods, and drink OJ. if possible get some iron in you. Feeling weak in the arm is fine i believe, but as soon as u said it felt COLD!... call ur doctor....</p>
<p>Natural blood production occurs in the bone marrow and it is hard to increase the rate at which it is created. Having had a similar experience in the past myself (I had wisdom teeth removed this past thursday and lost a lot of blood which made my face cold), I would try to rest and use a few blankets to stay warm and drink plenty of fluids with electrolytes. (This is what my oral surgeon advised me to do at least)</p>
<p>As these AP biol students should know - your blood was taken out of circulation - not out of your left arm. Your left arm was just the site where the sample was taken. So technically you have the same amount of blood going through you right arm as your left arm unless you have some occlusion stopping blood from going into your left arm. As stated before- if you are worried then you should call your doctor!</p>
<p>drink tomato juice silly! if your arm is still cold by monday call the doc</p>
<p>MagsMom, although you are right that blood comes out of the circulatory system, it is not uncommon to have people who have just drawn blood in extensive amounts from a specific region in the body to experience a "chilled" local effect. Blood is drawn out of the veins and when veins are punctured with a needle, blood will leak out for a certain amount of time until the vein is repaired. Since veins lack strong blood pressure, Oxygen deficient blood can seep out and therefore be less effective at warming a certain region. This effect is exacerbated when a person lacks adipose tissue to retain heat and many people have skinny arms. :)

<p>sanguine99 - apologies for offending you, I never intended on suggesting to you that you didn't know anything - in fact I thought your advice in post 4 was terrifiic - the line "as these AP students know" was not meant to be snarky - sorry if it came across that way -</p>
<p>I guess you learn something new everyday. I suppose I thought 3 tubes of blood and the OP did write bottles...so with that correction it would be considered an extensive amount regardless of the adipose situation. I would say though that if after 7 hours a person is potentially leaking out deoxy blood from a venopuncture site then that person should probably seek medical advice if they are concerned about a cold arm. Yes, local "chilled" effect can last - I suppose I didn't know it could last so long. Curious - are you interested in med school as your answer is so technically correct and succinct.</p>
<p>lol...just how LARGE were these bottles?</p>
<p>Just putting this out there, but maybe its more psychological than anything else (I'm not saying you're crazy). If people build things up in their minds or EXPECT something to happen, then sometimes they percieve that it does.</p>
<p>for example: I started getting allergy shots like a year ago. 1st time I went in and got a shot, I felt REALLY dizzy, like I was going to faint. I finally realized that I was playing it over in my mind, and the feeling went away. End of story.</p>
<p>Still, maybe call a doctor...I'm no expert.</p>
<p>Wow...I thought this was going to be a discussion on AP Bio. FRQ #4, lol.</p>
<h1>4 wasnt about blood, mcz..</h1>
<p>it was rather about the whole cardio-respiratory system..</p>
<p>i did mention hemoglobin as an oxygen carrier though!</p>
<p>I'm sorry MagsMom...I guess I was in a bit of a bad mood since I just had my wisdom teeth out and I have been taking vicodin to kill the pain of dry sockets. You're probably right that 7 hours is a bit too long for normal tissue repair to occur. I shouldn't have been so rude and bitter.</p>
<p>I guess having a mom who is always bringing medical terms and stories (no specific patient names mentioned, of course) to the dinner table has left an impression on me. Medical school would be an interesting experience.</p>
<p>Best Advice: If the arm is still cold, CALL A DOCTOR. I'm not one (at least yet :) )</p>
