Suggest Treatment For Painful Legs And Dizziness

I have suffered with aching legs - tight, tense muscles,soreness and sometimes cramps for the last year or so. The condition is especially prevalent after short amounts of physical work like d.i.y. or gardening,when my thigh and calf muscles tighten right up making it difficult to continue. I have had loads of blood test sand a doppler test and all have come back normal I also suffer with dizziness/vertigo quite a lot, though I not sure if the two conditions are connected,but they are really affecting my lifestyle and getting me down lately - can you help at all.
