Welcome to HCM.
Firstly I would like to clarify a few details.
When did your symptoms first start. Do you have a family history or past history of such complaints since childhood including cardiac or kidney
were they aggravated by your pregnancy
and were there any complications ?
In your case, the condition seems systemic or internal rather than just of the skin. The discolouration could be due to the fluid build up and improper blood flow. The upward progression of the edema could be brought on by the stress
of pregnancy on a previous problem.
I would advise you to firstly get a screening of your blood pressure levels and tests for kidney function, thyroid panel and cardiac too if required.
of your legs maybe required. Once these conditions are checked, the exact treatment can be started which MUST be taken regularly.
In the meanwhile, rest . Keep your lower limbs elevated whenever possible. Keep ur feet covered and don't stand for long periods.
Reduce your salt intake. Check your urine output.
The earlier you check with a physician the better.
I encourage you to do so promptly. Hope this helps.
