I am grateful to all of you who have shared your experiences. The chills just started for me about a month ago. My chills mostly come in the night, and get worse with the lack of sleep, but the onset seems to happen within 30 minutes of me eating. My tremors start at my waist and radiate down both legs. Tonight was the first night I timed how long this went on and I had the chills for about 30 minutes; subsided and then went for another 30 min; subsided again, and continued for about 3 hours.I too have had my blood work done and all is well. I am in pretty good health and 46. I have controlled BP taking triamterene 37.5mg/HCTZ 25 mg daily. I will be looking at my potassium closer. Nothing has changed in my life dramatically, or otherwise, over the past 5+ yrs. This is all a mystery to me. I too, will keep posting, should I find any answers. May God bless each of us as we walk this test.
I am not sure how long this has been going on but I experience extreme chills every evening. Last night it was so bad I grabbed a blanket, turned the heat up, put it on emergency heat, and laid over the vent for almost a couple of hours to attempt to get warm. I have extremely painful joint and muscles aches. I had a bad fall several years ago and have had pain since but this has grown in intensity. The joint aches have got to the point of not being able to tolerate it. The chills already started this evening...my laptop is helping me get some warmth right now I am not sure what to do at this point. Quite a few tests have been done including checking for metapause or peri-metapause...thyroid...and others...all come up ok. I feel everyones agony for sure. And as the chills come on every evening, the aches are severe to the point I can barely walk. Wish we could all get answers to tell us exactly what it is....until then we research and become our own personal doctors. Luckily I have a doctor I can ask to do blood work if I need to get something else checked. So I see a couple of things I need them to check for now.
I also have episodes with chills, they suddenly come on and i am completely debilitated, have to go to bed, chattering, can't even get up to put a pair of socks on. the episodes have been going on for about 4 years and are really bad, last about 2-3 hours, when i feel better, by evening i fall into a deep sleep and wake up ok next day. i thought these episodes could be panic attacks, but i have absolutely no anxious thoughts etc. I also have headache and nausea when these attacks strike. the only thing that i have been able to identify is possible chill eg getting out of bath/not drying hair and possible dehydration too. like everyone else here i would like some diagnosis as the episodes are really seriously debilitating and can strike anytime.
I have begun experiencing chilling at night, it wakes me up and lasts at least a half hour. Blood pressure goes up-no surprise, because it's upsetting. I'm 75 years old and it's new to me. Reading other notes on this site I've seen the possibility of nerve damage caused by taking the antibiotic Cipro, which I did late last year. Also low-dose aspiring which I take every day because of atherosclerosis and a 35-year history of cardiovascular problems. I also get an drip infusion of Remicade for Psoriatic arthritis every six weeks.
I'll take it up with my medical people and see if anything turns up.
I have been having these chill symptoms for about eight months now. I'm always freezing, and get the chills up my body, sometimes only in certain parts of my body like one leg at a time. I have seen three doctors and have had several blood tests done. They all tell me that it is stress related. The symptoms that prolonged stress may give you, in return, create anxiety, and sometimes panic attacks. If you search on the web "stress and chills" or "stress and being cold" you will find a lot of the same answer. This has helped me to not freak out when it happens, but I still get it. In addition to seeing a chiropractor, I have just started seeing a psychologist who says the same thing.

i think you may be right with regards to toxins, im beginning to think this may be related to gas, sounds daft but im going to get my fire checked out, its like im being poisoned, only had it fitted recently and i get these shivers at night more so in the cold when the fire is on, i only say this because my mum years ago had a gas leek and she has all the symptons of what you guys are saying, headaches, shivers that start in her legs, freezing cold etc etc .anna
