Synthroid and levothyroxin

I switched from a generic levothyroxine to Synthroid. After four days I awoke with extreme pain in one heel and the opposite knee. Both were caused by inflammations with no known cause in exercise or joint trauma. I switched back to the generic and both problems improved rapidly. Was Synthroid the cause? I don't know.

I have been taking Levothyroxin (Synthroid generic) for about 5 months. I started on a low dosage and have been taking 75 mcg (which turned out to be the right dosage. I turned 59 years old in July and I had been gaining weight.Nothing startling--a few pounds a years that added up to about 50 pounds over time..I am losing weight now. The side effect I am most concerned about is a an inarticulateness I seem to have developed since I started taking the medication.I can't sepak civilly to my son who also turned 20 in July. I just want to scream at him all the time.

Is this a side effect of Synthroid? I don't think I have been losing my hair, fortunately, but it is dry and brittle...

I have been taking Synthroid for at least 10 years. I am on a very high dosage now175mcg. I have been on a lower dose but my counts were still low so my doctor put my dosage higher. I have been having a tremendous amount of body aches including finger joint aches and right flank problems. I have taken x-rays and various tests to determine what the pain is but I feel that after reading much of the side effects from this web site, much of what I am experiencing is from the Synthroid or Levothyroxin. I now feel that I need to take matters into my own hands and do more natural healing. Many doctors don't connect the dots to determine the real cause of your concerns.

I have been taking Synthroid since Jan. 2006, am on 100mcg per day and all test results have been 'normal', I have been told to take this medication in the morning an hour before eating anything, if I do this...I have headache all day, I can't eat after an hour because I am so sick at my stomach there's no way. I feel hungry, but feel like if I eat it's coming right back up. Am having serious joint pain in hips, knees, elbows and wrists, my neck hurts really bad as well. I wake up to arms asleep anymore and just feel like I haven't slept in months...am very weak and very tired all of the time.

I have found that if I take my pill at night this gets a little better, but holy cow, don't tell your Dr. your taking it before bed...no, take it of a day. (don't know why this is a major thing?)

Anymore I feel like I am walking around with flu symptoms constantly, and the Synthroid hasn't done anything weight wise with me, because I was so HYPERthyroid before the RAI, I was very thin and looked like a bag of bones, have been waiting and excited about putting on weight...at one point I stopped taking the Synthroid and let myself go HYPO just so I could gain weight, it worked and I got up to about 130 pounds, was very HYPO so they told me critical that I get back on meds...I lost it again because it makes me so sick I can't eat.

NO-ONE can tell me the Synthroid is not the cause of this problem, if I stop taking it I feel WONDERFUL, but my test reults are bad. After a while of course my feet become numb and I end up having some bad hypo symptoms, have tried breaking pills in half....oh Lord no, need it all...

Have been told they are thinking about raising my dosage again anyway, I can't do this, I will break down in the office if they try to raise it. Right now my TSH is fine but my T4 is 'a tad bit' off. I am already an emotional wreck, if they raise my dosage I am going to try and go a different route with this, am on my 3rd Dr. at this point anyway...

I've been on levothyroxine for 3 months now. I have anxiety at night while trying to fall asleep. In the morning my hands feel so tight and are a bit swollen. My right knee and calf have started now too. My feet hurt when I get out of bed. After about 10 mins of walking they feel better. My face is also a bit puffy in the morning and I look tired all the time. I have pains on the right side of abdoman, just under my ribs....Is this normal? Could it be my liver from the meds?
