My Son, that is.
A few years ago he was diagnosed as having cancer of the thyroid. As they do, they promptly cut it out and after a course or two of radiotherapy he was deemed to be fit to rejoin the real world outside the NHS.
The problem with not having a thyroid is that your body is no longer able to absorb calcium. That means the boy had to take pills to adjust for that. Although these work, he has always had poor levels of calcium, usually about 0.7 (Somethings), whereas the recommended level is usually about 1.5.
Anyhoo. he spent last week in Scotland travelling and seeing the sites. However he began to feel somewhat ill and suffered from headaches at the end. A trip to his GP was in order.
The doc measured my son's calcium level and promptly told him to get his arse in gear and get himself down to the local A & E. The readings for the calcium level were 3.5 (somethings).
He's now on a saline drip, awaiting a myriad of tests.
And FED UP.
