I am living in Nicaragua and have been taking Metformin since September. I started with 500 mg regular, upped it to 1000 mg and got sick, backed off to 500 for longer, upped it to 1000 and got sick. I started taking the extended release metformin 750 mg (a more gradual step) and then 1000 mg ER and I didn't have ANY issues with the ER version. I recently upped it to 1500 mg (2 X 750 ER) It was fine and I wasn't having any side effects. Then my husband got sick and I got sick the next week (obviously not related to Metformin). I started with a stiff neck, then just not feeling good, I tested positive for an infection so I took antibiotics. After 1 week the only symptoms left are stiff neck that I can't seem to kick and chest pain that feels a little like asthma (which I have had since I was 7). I have not coughed at all but when I breath or swallow it hurts in my chest.
Sorry about the full medical history, I checked Metformin side effects and chest pain is listed as one. Has anyone ever experienced this type of chest pain. I am 38 years old, very fit (but overweight) and confident I am not having a heart attack. The pain is right in the middle of my chest. I am experiencing no wheezing or difficulty breathing, no heartburn, just constant pain in my chest which is exacerbated by breathing and swallowing.
My appetite has been pretty low since I haven't been feeling good so I think that, combined with the higher dose of Metformin is causing nausea. I am thinking about cutting back to 1000 mg because I can't handle feeling nauseous on top of the neck and chest stuff. I just want to be back to normal.
Anyone have anything similar? I know I should go to a doctor but here in Nicaragua medical care is not like in the US. They treat symptoms primarily and I am not confident that they can figure this out. My best bet, is to figure out what is going on myself and talk to a doctor about it. I don't need a prescription to get medication here. I can also go to a lab for testing without a doctor ordering it.
Thanks for your help.
