Hi Pete, I know your post was 11 years ago, but I found it because I am having the same symptoms. I just started Metformin a few weeks ago and I have developed a painful scalp and have consistent headaches ever since. The scalp is so bad it hurts to even touch it, and I wear a hat all day (bald guy problems) and it's super uncomfortable now. I am 49 and just trying to control my blood sugar as diabetes runs in my family and my bs levels have been hovering at 200-220 for a little while now. I'm fit and eat healthy, it just is what it is, **** DNA.
I was wondering if you figured out your issue or if you came off the Metformin. I am afraid to stop it without the guidance of my pharmacist, so I am currently waiting for her to call me back.
Thanks,
Brett
