Welcome to NeuroTalk:
One thing I see immediately is your use of metformin. This can cause low B12. So I suggest you get tested ASAP and have the results given to you (don't accept "normal") because labs have not changed their ranges to reflect the new protocols for IDing low B12. You should be at 400pg/ml in US units at least!
Here is a new video that explains how B12 is overlooked in the US today:

This is my B12 thread, with more details:

This needs attention now.
And yes, your back can contribute to PN damage in the legs and feet. Best to be cautious with heavy resistance at the gym.
Lower weight resistance and more reps is the way to go IMO.
