Hi there, I have been strugling with knots in my leg muscles for years, especially my calf muscles and started getting worse as i got older 40 - i am now almost 49. Problem is i would like to stay fit doing masters athletics / track & field and there is no way i can run (jog) further than 400m without serious lactic acid sensation to the point where i have to stop. If i break up the runs into shorter blocks i eventually have to stope due to 1st degree tears in my soleus or gasttocnemuis the junction in between them! This is really big problem for me but somehow i feel (hope) there might be a simple deficiency solution or remedy to sort things out?
