Hashimoto's Joint Pain

[prttypetunia_84]

I was diagnosed with Hashi's at the end of February. I am currently taking levothyroxine 75 mcg up from 50 mcg originally. My last test results at the end of April were as follows:

TSH: 4.85     Range - 0.27 - 4.2 uIU/mL

T4, FREE: 1.22      Range - 0.7 - 1.7 ng/dL

For the past few days i've been having really bad joint pain. I had this before being diagnosed but this is the first time i've experienced this since starting my medication. Could this be from my TSH not being in range yet, from the medication or something else entirely? Could hot weather be causing it? Sorry for all of the questions I'm fairly new to this.

I did not realize the joint pain was attributed to the thyroid problems. I had severe problems with both knees, hips, shoulders and then it moved into my elbows.
I had an RA test done to find out if I was positive. it came back positive. However my doctor told me that this was not the deciding factor on whethor or not i actually had it, only a helpful guide. I still have joint pain and have since been diagnosed with hyperthyroidism. So this is very interesting.

Your doctor needs to test Free T3, not just FT4 and TSH.

TSH is just a messenger hormone from the pituitary telling the thyroid what to do.  

T4 converts to T3 via the liver, however not everyone converts as well as they should. T3 levels correlate with joint and muscle pain, your cell tissue needs it. Most feel best with Free T3 in the upper 3rd of the range.

Even though I mentioned you cant just go by TSH, many people would feel hypo with your TSH.
