Erythyma nodosum and overactive thyroid?

[islasmum]

My sister, who is in her early 60's, has been diagnoised with having an overactive thyroid, and has also developed erythyma nodosum - large painful lumps on her legs.
She is usually very active, having her own smallholding and lots of animals. She was diagnosed about 3 weeks ago - does anyone have any experience of this, and any ideas on when she's likely to feel a bit better? (incidentally, she is under medical care, both doctor and hospital, I'm just curious; I've googled both conditions, but would like to hear from anyone who has experienced this.)

Is your sister taking thiouracil?

I don't know, Squad, haven't spoken to her for a few days and know that she's taking medication for thyroid, so she may be on thiouracil.

Well, I have never experienced this personally, but I have never heard of a link with erythema nodosum and thyrotoxicosis.

However, there is a side effect of long term thiouracil treatment which is erythema nodosum.

Ask your sister.

She has had EN before, about 40years ago - I'll try and have a chat with her over the next couple of days - I want to know how she is in any case. Thanks Squad.
