Bacterial lung infection? Opinions appreciated

Hi,
So I haven't been around in a while, Lyme is gone and have been very busy.

This fall, everyone in my community has had some type of contagious illness causing cough, congestion and sinus infections. No one that I know is seriously ill, and it's definitely not covid.

I had a bad sinus infection and cough that responded very well to augmentin, but as soon as I finished the 7 days, the congestion came back.

Now I feel like I'm drowning in phlegm but no fever and I don't feel especially sick, except I feel like I have brain fog and difficulty making decisions. The other thing is I suddenly have bruises all over my legs for no reason.

I'm wondering if this is mycoplasma pneumoniae or a different bacterial infection. (I'm assuming bacterial because the antibiotic helped.)

I'm probably going to go back to the doctor and ask for a test. I've been so busy, I forgot all about it, except that I woke up in the middle of the night feeling like I'm drowning in phlegm. Honestly, for me, covid was a lot easier

yep - as above - secondary bacterial infection due to primary viral respiratory infection is v common.

antibiotics can often help

it is often possible for them to do a culture of sputum to find which ones - but more of ten than not they just give a broad spectrum one to try to cover the bases - as its cheaper and quicker
