Over the last few weeks my right ankle/foot swells (not too badly) every day however i am experiencing a lot of pins and needles and some numbness in my foot/lower leg?

Sounds like you need to see a local health care provider about a possible sprain, strain, or fracture or other disease. Keep a diary about your pain and share with your team.

Your condition requires an exam as it includes gravity dependent edema and sensory symptoms. Several possibilities come to mind involving major organ systems and rather than my guess, I suspect you would prefer an accurate answer, best given following a physical exam, possibly with blood labs. In the interim limit salt intake, avoid salty foods, and consider graduates compression hose. Good luck
