hi,
Thank you for providing the brief history of your father in law.
A thorough assessment of the swelling is advised.
As mentioned that he is 75 years old and also there is a swelling in the lower
limbs, that is the ankle, how long the swelling being persisting. Also, is the swelling is a pitting edema or non pitting edema. To check this, you can press the ankle region where there is swelling, if after pressing the skin comes up than it is non pitting edema, if the skin does not comes up and the dent persists or takes longer time to get normal, than it is a pitting edema.
You may also need to explain if the has any high blood sugar levels. also, how is his
creatinine levels. Post taking the laboratory test for the - blood
glucose levels, creatinine levels and uric acid levels the next treatment will be applied.
Also, by keeping the leg over the pillow, the swelling will be reduced but getting assessed will be an advice. Also, you have to make him do long walking as his age is 75 and venous return has to be optimum to get the cardiovascular functioning.
Also, you may be advised to undergo
physical therapy - and they will help to learn the exercises to perform by which swelling will be reduced and also the strength in the lower limb muscles will be achieved.
Also, the treatment will be totally guided on the clinical assessment and laboratory findings.
