deep leg pain.could it be thyroid?

Hi Emily, Yes, muscle aches and pain can be related to low Thyroid symptoms. Also sometimes it can be a low potassium levels and low Vit D levels which are common in people with Hashimoto's and people with hypothyroidism.  You can take Vit D supplements and see if it clears up. Invest in a good muti-vitamin as it will help.   Consult with your doctor to have blood levels drawn for the above.  As we age, we do not make enough Vit. D from natural Sunlight and diet.  Now you have a long nerve in your leg called the sciatic nerve and it can be pinched at times, and cause numbness in toes and the leg area.  It can release on it's own. you can get an MRI, if it hurts for more than 7 days. 

Cancer does not cause aches, cancer is quiet and produces little problems until too far along. you would have low Red blood cells and sodium levels if cancer was a cause.

Try a heating pad on low to the area, and or a hot bath. heat relaxes muscles. Muscle rubs help too, and deep massage is helpful. You can ask the doctor for muscle relaxants like Flexeril Cyclobenzaprine), if pain worsens. Please have your doctor examine you for the above mentioned problems.

You need to have blood tests to check B-12, VIt D, RBC's Sodium level, Potassium Level.  For peace of mind.   I hope this helps.

You could be going through an overactive phase. However, I would go back to your doctor and ask as it could be something else. (No idea what, it's just that thyroid shares symptoms with so many other things).

Emily, Please see your doctor.  Many thyroid patients get low Vit D levels and many also have other low blood B-12 and potassium.  You need these minerals to be correct in the blood. Also have your Blood Glucose level checked. Some people get Diabetes and do not know it.  I also recommend a check for Lupus & Rheumatoid Arthritis, as these  can occur in some thyroid patients. Can you call your doctor and make an appt. to see him/her?  This would be wise to do.

Hi Emily,  Yes, low  B-12 levels cause Pernicious Anemia and it is not replaced by diet or regular vitamins.  It can cause problems like being very tired and having low energy. If yours is okay, that is very good.  The only way to replace it, is by getting B-12 injections. Some people can have muscle pains from the level being low.  You need to have your Vit D level checked as that can go low and cause muscle pains, brittle bones, etc....

A few tests should be:

1. Vit D level

2. Potassium level

3. B-12  (you had this one done)

4. Lupus & rheumatoid arthritis markers.  Because of Hashimoto's these are auto-immune conditions and you could have it also. It may not be, but most of us are tested for these to RULE IT OUT. 

I suggest you tell your Mom, you need to have peace of mind and ask for her to understand why you need these tests. You did not know to ask for these tests before.  You can see if maybe the doctor did already test you, can you get a copy of your recent bloodwork tests from the doctor's office?  Go to a good GP or Endo doc and log your symptoms in a book and then bring it with you to the appt.  It is helpful to show patterns of when  you have the pains. I hope this helps.

By the way, endo means Endocrinologist - a doctor who specialises in the diagnosis and treatment of diseases related to hormones (e.g. thyroxine).
