Did I have magnesium overdose?

I was taking albion magnesium, 133 mg twice per day, then on Friday night took extra 266 mg and Sat. took about 1200 mg plus another 200 mg in calcium supplement. By Sat. night I was starting to swell on my face and break out in hives. I had not changed anything else in my diet...only the increased magnesium.

In the following days my arms and hands swelled, I had hives and welts all over my body, my lips swelled. I stopped ALL supplements Sat. night and by Tues the increased symptoms drove me to immediate care facility. The doctor had blood test done for magnesium level and kidney function which came back normal.

I have seen several doctors since this started and none thought it was magnesium, but I do because it happened right after increased dosage and I had changed nothing else. It is now Sat., a week later, and I started getting better yesterday, but still have red spots, hives and low level itching. Could this have been a magnesium overdose reaction? Oh yes, I did have loose stools which is most common overdose symptom.
