I'm not on beta-blockers and my thyroid seems to be "within normal range" however, I'm having orthostatic hypotesion with increased heart rate, dizziness, and some ocasional tingling in my hands. Everything started with an anaphylactic reaction to what's suspected a spider bite siz weeks ago. My allergist says that at this point is not the allergy (which he confirmed with blood test) and that it might be my thyroid. My endo checked my thyroid and it seemed fine and also check for adrenal ABs which were negative. My GP has checked for the presence of viruses with all results negative. I don't mean to put you in the spot or anything, but if you have any idea it'd be greatly appreciated as right now, my Drs are out of fresh ideas. Thanks in advance! greatly appreciate your input and advice and taking the time to post on this forum.
PS I was on prednisone for 4 weeks (2 weeks ago), and currently on anti-histamines and tapazole if that helps
My GP tested me for Lyme and it came back negative. I don't remember any tick bite but you never know as I spend (use to) a lot of time outside. So that's why my GP decided to r/o Lyme.
Did your RN friend tested negative for Lyme?
Thanks again
PS I hope you get better soon too
did you feel significantly better on prednisone then get worse after stopping it? Anti-histamines could do it - do they have sudafed in them (ie allegra-D, zyrtec-D etc)?
Other thoughts - acth stimulation test for adrenals (esp if symptoms got much worse after stopping pred). Tilt table test (with a cardiologist) - most helpful if your symptoms are dizziness, nausea and sweating with prolonged standing - may not apply in your situation. I presume your calcium, potassium and magnesium are normal. A rare cause would be pheochromocytoma which is an overproduction of adrenalin - usually tested with 24 hour urine collection.
The spider bite history is interesting and may be important - I will think on that....
Dr Mark makes some interesting suggestions as well...
I actually started to feel better when the prednisone was reduced and when I stopped it. Dizziness was better and heart rate although high was not as hig as it use to. Before it'd be 92 resting increasing to 120/130 when standing. Now, it goes from 80-85 resting to 92-95 standing. Sometimes it settles after a few minutes and sometimes it doesn't, forcing me to sit down again.
I'm not on sudafed, I'm on allegra, ranitidine, and zyrtec (I know it sounds like a lot but it was bad reaction - I guess I can talk to my allergist to reduce it). Yes, all of my electrolytes are fine (sodium, potassium, etc.) In fact, all of my blood work always comes back fine.
Thyroid has been checked three times and always comes back fine. TSH ranges b/t 0.58 and 0.76 (don't remember the T3/T4 but are ok too).
So you can see why my Drs are out of ideas.....but trying
Still_Hoping, Thanks for your message - I guess it doesn't hurt to get tested for Lyme again as ABs can be tricky to detect I hear. I know that Drs don't have all of the answers all the time, the human body is a mistery and science is still working on it! I know of cases in which people get sick and get better and they never know what happened to that person. However, I think that good Drs are those that care, don't think that what you're feeling is in your head and continue trying. Even if they can't find anything, they listen, don't think you're crazy and care. Your friend's example it's a good one in which they'll never know what happened to her. Maybe the antibiotics worked or maybe she just got better by herself, but she had a Dr who tried to help (well, personal interest but there are Drs like that out-there)
Thanks to both of you, anything you can think of is welcome. I'm ready to feel better!
