Thanks for posting your query.
As you are experiencing feet swelling, make sure it is not due to constriction position causing compression of vessels and swelling. Any sprain
& strain may also cause pain and swelling. Rule out Deep Vein Thrombosis
, cardiac and kidney
You are advised to visit your doctor and get necessary tests like ECG, urea & creatinine
,TSH & T3, Doppler U/S etc to rule out conditions.
Hope it helps.
