I Drink Plenty Of Water And Get Adequate Exercise. I

I drink plenty of water and get adequate exercise. I am 44 yrs old and do not smoke or drink. I do not use drugs and am not on prescription meds. I urinate very frequently and it has the odor of almonds. In the past 2 years I underwent extensive vein removal surgery on my left leg and have constant numbness and sometimes vice-like pain. I walk often to increase circulation but my leg feels heavy and swells, especially at work where I sit for hours. Please help.
