I have swollen feet which pitt 3 months after chemo TAC.  I also get a tight throat and breathlessness.  I do have a chronic lung condition which I have been told in not sinister.  I was really fit and finding stiff legs when getting up or after sleeping a pain in the neck.
Thanks for your question on Chat Doctor. I can understand your situation and problem. Swelling and stiffness in legs is commonly seen in right sided heart failure. You are also having chronic lung disease. These diseases in the later stages cause right sided heart failure. So better to first rule out this. So get done ECG and 2d echo. If both are normal then no need to worry about heart diseases. You also took chemotherapy. And sometimes chemotherapy can cause renal damage. This can also cause lower limb swelling. So also get done renal function test (creatinine and urea). So consult doctor and discuss all these. Hope I have solved your query. Wish you good health. Thanks.
