carpal tunnel

Hi, am new to this site.

Have been on levo 150mg for 10 years no problems. however recently my old carpal tunnel symptoms have retuned, along with very weak arms and legs. I therefore had tsh test and result was 1.17.

however 3 months ago my pharmacy changed levo manufacturer to Teva, who have only just got their licence back after 5 years for giving out inaccurate dosages, so I have been on Teva levothyroxene for 3 months so have now changed to mercury thyroxine and been on it a week as I dont believe in coincidences re Teva. Still no improvement though and my legs are even starting to give way. would appreciate any comments plz.

You need to have a new blood test. Ask for TSH, T4, T3, Free T4 and Free T3 and also B12, Vit D, iron, ferritin and folate.

The test has to be the earliest possible fasting and allow a gap of 24 hours approx between your last dose of levo and the test and take afterwards.

Levo should be taken with one full glass of water and wait about an hour before eating.


Get a print-out of your results with the ranges and post on a new question.

shaws Hi I was just going to suggest B12 testing but you beat me to it. The carpal tunnel and legs could be that.

Hi, I had a colleague who had two injections for carpal tunnel syndrome and was due another followed by an operation if it can we back again. She started taking a vitaminB6 supplement and after 3 months her symptoms had significantly improved. Now she has no issues at all ( unless she doesn't take her vit). She never needed the other injection or the operation.


I assume that you have not already had any ops for carpal tunnel. If not, then get a referral to a hospital where electrical tests can be carried out to establish the extent of your troubles. A couple of small operations under local anaesthetic and without an overnight stay can easily give you immediate relief. No supplements or other medicines were ever offered to me as an alternative to ops.


thanx for responses, however I want the cause treated not the symptoms, which I will tell the doctor when I see him.


In my case and for many others the CAUSE was taking levothyroxine. I cannot imagine that many doctors would be prepared to admit that to you openly.
