Side effects from taking levothoxorine and synthroid

[Brucergoldberg]

Im just curious what sort of side effects people get when they start treatment.  I think that Ive gotten a whirly sensation in my head, sometimes I get these weird crampy headaches that come and go rather quickly behind my temple.  Also I get this weird metallic feeling or "electric" sensation through my body.  I know I may be off base but does anyone else get any of this?

Also my memory is terrible.  Concentration bad too....

anyone else?

I dont know if its any consolation to you Bruce but I got a .metallic; taste in my mouth *like the taste of a metal filling) but this was when I was hypo and not hyper.
I had it when I went hypo after RAI and it tastes foul.
I used mouthwash for about 2 months until my TSH started to go down and my levels evened out.
As for the headaches.....I have sometimes got a headache about an hour after taking thyroxin (aussie thyroxin) but it soon passes.
As time has gone by and my body is used to the T4 med, the heaches are less frequent.
I very rarely get them now.

There are 2 brands of thyroxin in Australia........
one brand has stereate talc (filler) in it ...the other doesnt.
I cannot take Eltroxin that has the stereate talc in it.

I have had many neurological issues since my hypo diagnosis.  I was originally hyper years ago when I was diagnosed with Graves, which quickly went into remission.  I then became hypo and was put on levothyroxine.  I'm not sure if if was the levo or the fact that my meds needed adjusted, but I had a wave of strange and very scarey neurological symptoms come in all at once.  New symptoms showed up for a good 3-4 weeks.  I had cognitive issues (confusion, concentration problems, replacing the first letter of words with the wrong letter, vertigo, numbness of the face, forgetfulness, balance problems, etc.) and I had an array of tests done for MS, etc.  Tests for anything else were negative, but I did have some minimal nerve damage from whatever happened, and since then, I always get the "electric" sensation.  I get it so bad that it feels like beestings and hurts.  I get these adrenaline rushes that are accompanied by the tingling/electric feeling.  I hate it.  I even get these and heart palpitations, etc. when the docs say that my levels are "normal." I always think there's something else going on that they haven't caught since they always say "well, your symptoms are not from your thyroid....your levels are all normal."  I also have antibodies for Hashimotos so maybe having antibodies for both Graves and Hashi's can cause some...who knows.  Honestly, I don't think the doctors really know themselves sometimes.  
I will say that the only change they made was that they modified my dosage and put me on actual Synthroid instead of Levothyroxine.  Those were the only two changes that were made by my Endo.  I have been feeling much better, although not 100% symptom free.  I'm not sure if it was just an attack that stopped on it's own, or if these modifications helped.  My Mom has to take Armour (sp?) because she has allergic reactions to Syntrhoid.  Sorry, wish I could be of more help to you.  I hate to hear that you are suffering so bad.  If you are not happy with your doctor, change to one that will take the time to work with you until you feel better.
Best of luck!

I don't know about electric things but with levothoxorine I felt good but when the doctor change my medication to synthroid I had hives, chest pains, my tongue was numbed and was having trouble breathing. The doctor said they were both the same thing but it could have been the formula how they were mix.
