Thyroid making neck itchy

[Kews77]

I have noticed since the 1989's with the introduction of Rapeseed being grown that allergies of all sorts have grown.  Myself, I never had any allergies until I moved into a rural area where Rapeseed seem sto be covering much of our fields.  I know for a fact that I have an intolerance to Rapeseed.  I have an odd situation happening and can only link it to Rapeseed as I have had full blood tests done with nothing being shown to be out of sorts.  My Thyroid gland swells up when the Rapeseed season gets its grips on our surrounding area.  I have to drive now with my air controls off in the car as I find the smell so overpowering of the Rapeseed.  My Thyroid has taken on an Itch Allergy now which goes if I put antihistamine cream on my neck where my thyroid is.  I also take liquid antihistamine which helps with my throat.  I do wonder if there is a correlation between Rapeseed and all these allergies.  Rapeseed is grown all year round so for those who suffer all year round is it possible the link is Rapeseed?

Hi, yes I had read somewhere that it causes goitres.  My thought currently is that we are surrounded by the Rapeseed and this is the first year my thyroid has actually reacted by being itchy.  I have found relief with a prickly heat spray which seems to have calmed it both externally and internally.  I find it interesting that no real analysis on Cause and Effect are being carried out in local communities living with this stuff in their environment.  You would think that the Doctors would've more proactive with surveying their patients and ailments and perhaps coming up with some sort of conclusion to the safety of this product.  After all it was grown initially for Mustard Fas and then later for the motoring industry.

Interesting.  Let me first say that Americans are by and large not familiar with rapeseed or rapeseed oil.  We are much more familiar with it's cousin, canola, which was bred (traditional crossbreeding, not GMO) in Canada to exclude the chemicals in rapeseed thought to be toxic.

Both are related to cabbage, which is a known goitrogen (causes inflammation and swelling of the thyroid).  If the plant has it, its pollen probably does as well.
