Muscle Weakness and Aching Joints
Waking up with stiff joints or feeling uncharacteristically weak when climbing stairs often gets dismissed as arthritis or a natural loss of muscle mass. However, thyroid dysfunction triggers significant musculoskeletal problems.
Hypothyroidism frequently causes generalized joint pain, carpal tunnel syndrome, and uncomfortable fluid retention around the major joints. Hyperthyroidism, on the other hand, can actively degrade muscle tissue over time, causing noticeable proximal muscle weakness.
This specific type of weakness makes it exceptionally difficult to stand up from a low chair, wash your hair, or reach items on high shelves. If your strength rapidly declines or your joints ache symmetrically without a clear physical injury, your physician needs to evaluate your endocrine health rather than simply prescribing more pain relievers.

Thank you very much this information is very appreciated many women on my mother’s side have had to take medication for thyroid imbalances including myself.
This information is incredibly helpful regarding my thyroid condition. Thank you so much for this educational materials.
I am 73 y/o and lately around 11am I feel like very sleepy and wanted to go back to bed again inspite that I slept about 6-7 hrs already during the night. I could bearly function especially after lunch time.
I take levothyroxine 0.88mcg daily for how many years. TSH is being done routinely e.g every 6mos or one year.
What do you think about my lethargy? Good thing I am retired now.
