To blackviper,

please update on your progress, I think the advice regarding diet and muscle tissue is sound and reasonable. Considering you have been active, is this activity greater than usual? Local massage may induce lymph drainage of waste materials and re-balance lactic acid buffering systems. I believe H+ and acidic environments influence cramping:

As mentioned previously:

Glucose + 2 ATP + 2 NAD+ + 4 ADP + 2 P ====>
2 Pyruvate + 2 NADH + 4 ATP + 2 H+ + 2 H2O

If insufficient enzymes present, Pyruvate is converted to Lactate

Pyruvate + NADH + H+ ====> Lactate + NAD+ + 2 H+

H+ buffering by increasing cellular muscle carnosine levels is now being shown to improve sporting performance.
