Have you had your vits checked, numbness in hands etc is often associated with low vit B12, hairloss with B vits and ferritin, Fatigue with B12, ferritin and vit D. We often dont absorb nutrients well, which has a knock on effect on absorbing our levo fully and then converting it properly.
Try to get B12, Folate, D and ferritin tested if not already done and post any results with ranges on a new post for advice as these must be optimal not just in range to telieve symptoms and convert properly! My fatigue has improved a lot now my deficiencies are being resolved and I seem to have a bit of thin fuzz appearing 🤞🤞it continues to grow.
Long heavy periods/frequent bleeds can decimate ferritin levels. I am not aware of clots being a symptom but it is always possible. Alternatively, you could have an underlying gynae problem which is showing now your thyroid levels have improved, low thyroid levels could have been masking it. If GP thinks not thyroid related ask for a sex hormone panel or gynae referal to rule out things like PCOS (irregular periods (not always absent), weight gain, fatigue, hair loss, inappropriate hair growth, spots or any combination of...) or any other dysfunction as like the thyroid its all part of the endocrine system and often more than one bit will be misbehaving.
Have you seen the symptom checklist on TUK, you may be having a lot of small symptoms you have not connected and he will be hard put to ignore them all. also some good advice I was given.....
Be specific especially when describing things - eg I used to be refreshed after 8 hours sleep now I wake up still tired after 10. I used to enjoy taking my dog for 5 mile walks, now I barely have the energy to leave the house or whatever fits your circumstance.
It means you are describing a quantifiable change rather than a more airy-fairy 'oh Im just tired all the time' it makes it slightly harder to be dismissive as you can start asking awkward questions like if its not my thyroid then what is causing it and what are you going to do to fix it - do not accept (if applicable), its your age, what do you expect with kids or similar.
Definitely read up, take print outs or a tablet with you and highlight relevant bits, phone up and get any blood results before appt or telcon with GP so members can help you interpret and give suggestions. Take a list of questions/someone with you if you get a bit foggy.
