Such a pain is really worse and makes us feel very bad about it. For a immediately relief, I will suggest you to take Anti - Spasmodic medicines so that your pain in the abdomen gets relieved. I will suggest you to visit your local doctor or Homeopath
to get immediate treatment.
Further, I will suggest you to have a Complete Blood count
(CBC), a Electrocardiogram (ECG) and a Ultrasound Sonography
(USG) of your Abdomen and Pelvis.
By these 3 investigations you will be able to know what is the underlying cause for the swelling of your feet, hands and hands with legs.
With Warm Regards
