Check out f2c electrodyrance if you are in the us or Canada. I don't think there is a better option at a better price. Although i think in response to the original question, electrolytes aren't going to do much for you if your muscles aren't properly fueled. I like maple syrup for cost effective running nutrition. Table sugar is probably even better from a cost standpoint.

I get some groin tightness every now and then and just use a massage gun on the area and it goes away before it blows up. Sounds like you'd benefit from one.
