my father s left thigh is swollen. Has CHF, veinous insuffency, and has had celluities ( about 1.5 months ago) in leg but it has cleared up now. has had poor circulation in legs, feet also. Legs and feet are not swollen now, just upper thigh, expecially aournd inside and back near knee. What could be causing this? His abdomen is also swollen, bloated but doesn t hurt, just uncomfortable. Has amenia and been taking iron suppliments about 2 months. Can the iron suppliments cause stomach bloating?
