Undiagnosed Lightheadedness/dizziness

[gilyarj]

Hi
I have been dizzy for about two weeks now. It is a very slight dizziness that is very familiar to the lightheadedness you get when you stand up too fast. It started after a trip to the dentist. Later in the evening after the dentist I almost passed out and my heart started racing for a very short period of time. The lightheadedness/ dizziness lasts all day long and varies in intensity getting worse when I sit down.

I had very similiar symptoms a few weeks later after my first visit to the dentist. This visit left me with a bad headache for about 10 days and few shorter episodes of dizziness.

I am someone who exercises heavily everyday and I have been able to ride my bike throughout these two episodes including competitive racing the weekend before my second visit to the dentist. What bothers me now is that my last two attempts at cycling have left me with bad episodes of pounding heart, nearly fainting, warm feeling of adrenaline in my chest, chest pain and numbness on the left side of my body. This does not happen directly after I ride, up to severa; hours later and i feel real good while cycling. Cycling actually makes the dizziness go away.

I have been to the doctor a couple a times including the emergency room after the last cycling related episode which was really bad. I am not someone to go the ER very easily it was scary. The ER ruled out heart attack and sent me home since I was scheduled to see a cardiologist the next day for an echocardiogram. I have had an three EKGs so far that are normal; and blood work (CBC) and electrolyte panel that are normal. The echo at the cardiologist ruled out structural defects including an enlarged heart septum which is common in young athletes. I am now hooked up to portable heart monitor to record any other episodes. I don't think it will be helpful since I have had vitals taken a couple of times now while not feeling good (ER, and Cardiologist). I am scheduled to see the cardiologist again in a month and he seems pretty ambivalent to the fact that I want this fixed now.

My father has a history of some of the same symptoms that have gone partially undiagnosed. He does have spells of dizziness and headaches but they seem to only last for a few hours and very infrequently. Were I have been dizzy for two weeks now. He has worn a portable heart monitor for a month also and nothing has been found.

Any help would be appreciated.

hi there..hope by now, you are feeling better..
I had some similiar symptoms after an extraction at the dentist...after many attemps of finding out what it really was...it came out that due to infected tooth i had, the bacteria when up to my ear canal and infected it...well, i did not have any ear pain or anything, i though it was the infected tooth...

but this infection caused my inner ear to be infected, and when this happens, you do have dizziness and headaches too..and when i would get up, or walk around, i would get dizzy...until my gradma, said to go to a EAR,NOSE,THROAT DR...or ENT...

THATS when they found out i had an severe infection in my inner canal, and gave me some medicines and did something with a syringe in my ear...didnt hurt either..just uncomfortable...

after that, 2 weeks of antibiotics, the infection was gone, and my dizzines went away and headaches...

hope yours is as easy as mine was...
if you read about the ears, you will find that the inner ear are responsible for our balance, too...

well hope this helps ok...take care and hope you feel better soon so you can enjoy your cycling and the outdoors...

take care

why did you have to see dentist two weeks ago ?, maybe it is something related ?

It sounds like anxiety, or anxiety attacks. Stressful situations (like visiting the dentist) would be a stressor, and one of the "cures" for anxiety/attacks, is exercize.

Any trouble breathing?

Anxiety attacks seem to come from nowhere, and it feels like the end of the world. The first time I was diagnosed with anxiety attacks, I thought I had a lung infection.
