I should clarify also, ice and heat in alternate sessions can help alot, just don't use it as a way to keep going. Icing in particular can relieve a lot of the pain and inflamarion but the temptation is to keep going once it feels a bit better, and that is a mistake.
Heat and ice is for recovery time.
A lot of very firm massaging with a rounded object, i use a two inch dowel with a rounded end, right into the sore spots, can be downright distastefull, but it'll help. As firm as you can stand, don't muscle against it, stay relaxed, but it'll help.
An increase in potassium, calcium, and magnesium intake can help as well. Alfalfa taken as a supplement can be nearly miraculous as well.
