Hi, I tried to post to your question a day ago , but see it did not make it, I too had all those symptoms you speak off, except I also would suddenly get very cold hands and feet , then go into a sweat which was body wide, meaning legs ,everything,very nasty, and so in response would cover up, but the sweat was crazy,with goosebumps on my arms, this was not like a sweat you get when you workout or have a fever, as a matter of fact my temp would be around 96.4 ect....,this would come and go for about the last 5 months, yes I did go to my doctor,but it was brushed off as a virus ect..., well Feb 12 it started up again, and by mid day I was having some serious issues trying to catch my breath and that damn sweat had me down on the couch, mopping it up with a dish towel, my daughter begged me to go to the ER since I do have heart disease, so off I went, well....I ended up in the ICU, because the evening off the er visit I started have tar like bowel movements,I ended up having 4 units of blood given to me, and was still 2 shy, that the Docs said my body would make up for, when asked why it took this long to find out the problem the Doctor said everyones blood volume is differant . so you can be 2 pints shy with out it causeing alarm,so in the beginning of this nightmare I was loseing blood slowly,due to a ulcer in my small intestine,so I guess I would advice you to see your Doctor again, and see if you can get your stool sampled,on the off chance that you have the same problem I have, hope I was of some help, Diana
