Have you noticed an improvement with the itch using this new cream?
The product you are using has three actions:
salicylate: removes excess scales from skin
hydrocortisone: reduces inflammation/redness and thins skin when used over time It has a benefit of reducing itch relating to inflammation.
sulphur: anti-bacterial action
So using this will remove the excess surface layer of the skin and allow the small capillaries under the skin to be more visible. It may also allow more easily the normal hair follicles to be visualized and does not mean that you have ingrown hairs all over.
This cream should only be used on areas as directed by the doctor and for limited periods as excess use can cause skin damage. If you are seeing more visible bruises then you need to have your INR checked. Do you know your latest INR?
The triamcinolone causes this effect of skin thinning and also increased risk of 'striae' or purple stretch marks.
Without seeing these marks then I cannot be definitive however the other possibility is that these are 'purpurae' or petechia (small clusters of capillaries bleeding). Even when INR is normal, other things can interfere with the other clotting factors leading to increased bleeding. If you feel unwell then you should see a doctor over the holiday. If you are feeling well then it may be alright to wait until after the holiday to see a doctor.
Have you noticed any change to color of urine?
Have a look at these images:
Basically there is small amounts of blood leaking from capillaries under the skin.
I would like you to see a doctor today. This type of problem may simply be a side effect of your medication and the coumadins, however it can rarely be associated with endocarditis (and I'm thinking of your valve here) and also some auto-immune or infective causes.
You need a check up in person and some blood tests. You may even need an echocardiogram depending on the results of examination.
So you will need to go to ER or urgent care clinic in your area.
