As far as medical problems stemming from shocks, they can be anything from nothing up to death. One can get heart problems or neuro-muscular problems from even a mild shock, or even brain damage. It also depends on where you were shocked, as well as voltage/current.
I have been severely shocked 3 times in my life. When I was indirectly hit by lightning, I suffered palpatations for a few days. When I was working on an old tube Oscilliscope, I got 120V hand to hand. I didn't suffer physical problems, but I was slightly traumatized by the incident (I went as far as shutting off the breaker when replacing a light bulb). The third time is when I rented an amplifier for my band. The amp had a 2 prong plug, and the case was grounded by the hot through a capacitor. When the guitarist handed me his guitat while I put my fingers on my bass to prevent feedback, I received a mild shock. I didn't even feel it at first, but then it progressed worse and worse. I suffered palpataions again as well as breathing problems, and was hospitalized for observation.
Electricity has to be respected. If there is any chance that something may be live and exposed, use PPE. When I work on tube amps, I wear rubber gloves (I forget the rating, but I think up to 1000 Volts).
scott2828, Welcome. It's good that you're getting checked out. Even if you felt fine, I'd still recommend it - better safe than sorry.
