@gently Thanks for the response. My next appointment is this Thursday at which time I will be meeting with the doctor before heading into the next room to receive the injections. The dizziness lasted on and off that one morning and was not accompanied by any other symptoms. The nausea came on a separate day. The following month the dizziness wasn't as strong and didn't last as long. But it did occur. It was similar to vertigo where you see the room spin. I find it odd that both times the symptoms didn't occur until basically 20 days after the injections. That's why I didn't make the connection the first month. But as you said, I think it best to ask for a blood test. I'll circle back on Friday, letting you know what the doctor had to say.
