** Thanks for contacting with your health concern 1. You need medical evaluation since it could be a blood clot [DVT- deep vein thrombosis] which has to be immediately excluded as there is a pain in the right leg [one week], so seek immediate medical intervention [vascular surgeon opinion] or visit an ER. PS. In addition to above cause, one may exclude simultaneously: nerve damage [neuropathy], high uric acid, or any poor circulation to the foot [any peripheral vascular disease/diabetes] 2. It is important to consult with Orthopedic surgeon/Podiatrist to prevent further or long-term damage since failure to do so can lead to disability, paralysis, permanent symptoms of pain and numbness.
