Levothyroxine Sodium and levothyroxine

For the last year and a half I have taken Levothyroxine Sodium 50mg, now increased to 75 mg. I have gained a great deal of weight and developed arthritis in both knees. Some days my knees hurt so bad I can hardly get out of bed. Since my medication was increased to 75mg. I have been itching like crazy. It is not continually, but at times I just go into an itching fit. Please help! Is there any other thyroid medication that works without all the bad side effects?

I have taken this Levothyroxine ever since I got Thyroid Cancer in 2006. And thank God I am free from cancer now. My main problem now is that, sometime I really don't know what was wrong with me and get confused over my own feeling. I do have cramps, sleep problem, headache, menstruation problem, mood swing, panic attack and always thinking of a negative thing eg like am I going to die. It has been bothering me since than. Please help I just wanna know is this really due to the medication or its really that I am going to die. I am very confused at times when feeling this side effect. =(

I have been taking levothyroxine for about 10 years now, i have had the following symptoms with them, weight gain, hair loss, mood swings etc, but i can also put it down to having a Mirena coil. The main thing that has concerned me is that i started to have panic attacks over a year ago with severe depression to go with it, my life was fine before that, had no problems, 3 wonderful children, my life was great.
Does anyone know of any other medication/natural products we can take?
I'm just so fed up with feeling like crap all the time.

Hi, i have been taking Levothyroxine for 10 years now, and at the moment i have been prescribed 100. Four months ago I start having horrible panic attacks and my anxiety have increased since. I went to a private doctor and she stated that everything is happening to me is because of the Levothyroxine and i should change to natural. I am not sure what to do , i just really want to feel good without this horrible anxiety!!!!!!!!!!!
What i should do?????

Started taking Levothyroxine 100 3 weeks ago, for last week I'm in agony, my joints and muscles are sore, specially legs and arms, got constant headaches, mood swings, I'm also short of breath which developed before muscle pains, went to the doctor, was told it's probably asthma (!!) got tablets and inhalator and he mentioned anxiety, when muscle pains started, went back, was told that it's not related with hypothyroidism or Levothyroxine, it's a virus (??) have to drink plenty of water and got Diazepam and link to anxiety website. Help, it's not stress related! I don't know what to do!! Does anyone know how to get rid of those pains?

hypothyroidism- since August 2007
I went for a second opinon and he started me on Levothyroxine .50 3months later increased dose to .75.

I have put on some more weight, losing my hair, but I am sleeping better, this has helped me with my panics attacks, and I have little more energy.
I can not complain. I know it takes time to get it right.
