Is this normal? Alcohol causing symptoms to return 1.5 months after concussion
I had a concussion 1.5 months ago, but 2 nights ago I drank literally only about 1 standard drink, and felt a bit lightheaded and "slow," again, and then had headaches at night and the following day. Now I'm overthinking that I very slightly/lightly bumped my head while entering a taxi that night as well and whether I gave myself another injury or something.
The days immediately before me drinking again, I felt symptom-free, by the way.
This sort of return of symptoms also happened to me about 3 weeks ago, where I drank and it seemed like symptoms returned, but that time I drank maybe 3-4 drinks, and it was closer to the injury so I figured it was more normal.
Is this common/normal? Will I just never be able to consume even the slightest alcohol without feeling bad for like 48+ hours again and feeling symptoms return?
Have I permanently damaged myself by drinking even slightly while recovering from a concussion?
