Alcohol and Lower back discomfort

I’m a 29M, 165 lbs.

So about 3 months ago I started getting some lower back discomfort. At the time I had just got prescribed Adderall also. I take it at like 6am during the week and its a low dose of 15mg xr.

I drink socially, usually Friday and Saturday, none during the week. I took a break in August and didn’t consume any alcohol for about 4 weeks (just to detox and reset my body) The back discomfort completely went away. I have also been running around 10 miles a week for some extra exercise because I sit a lot at my job.

About 2 weeks ago I started drinking again and now the back discomfort is back and the only thing I have changed is the consumption of alcohol.

Has anyone else ever experienced this? I’m just trying to narrow down what’s causing this.
