I've seen it mentioned, but my search results turned up nothing, so now I'm looking for others.

I know I should be asking my doctor but I'm currently between endos and pcps, I'm just asking if anyone has been told they're linked.

I've been on metformin for 24 years. Recent eGFR results have come up in the 45-50 range leading them to diagnose me with ckd 3a.

I can't take Lisinopril or the similar drug due to passing out from low blood pressure, even at the lowest dose

I had a pcp question why I was on metformin as a t1. I told him because I have insulin resistance as well. He didn't question the actos tho, which is definitely a t2 med usually. My sugars tend to run higher without metformin but, I'm wondering what the trade off is.

Has anyone been told their metformin caused ckd or is making it worse? Were you advised to stop taking metformin even if it was not the cause?

So background, I've had a slow growing set of masses on my leg for two years now, except it's now speeding up. When I went to a surgeon last year she said it was a bunch of lipomas, and without imaging beyond an ultrasound and no biopsies, said my nurse will schedule you for surgery in the operating room, on the biggest one only. Then talked to me about weight loss surgery for 30 minutes.

Now I went to see a new PCP and he told me some inaccurate things that I know we're glossed over in medical school (I have a host of other chronic illness and I just need him to cover me till I get in with a new specialists), and being young, I'm sure he hasn't encountered.

He said the largest mass has quadrupled in size in less than a year, so it is significantly larger than a softball, unknown size exact because there was some edema blocking the second ultrasound, but effectively 11 inches across and has an open wound where it gets rubbed. The lower leg has developed similarly, now with skin involvement that looks like it could be a skin cancer.

However he told me a few things about the potential cancer diagnosis that has me questioning him.

- oncology doesn't do diagnosis, only treatment

- there is no need for urgency in a CT scan (especially since I have an MRI scheduled for the 12th, but I'm afraid my apron belly will stop me from fitting in the machine)

- he doesn't want to do contrast with the CT scan, because of chronic kidney disease stage 3a, which is where they make you stop taking certain kidney heavy meds but it's still safe (another thing he told me that I have more experience than him in)

I'm not really panicking or anything, I just don't have anyone to talk to about this stuff, and like I said I'm questioning my doctor who has a "it's true because I said it", pov with other things.

Any insight on the things I'm questioning?
