I have ET and am on HU and aspirin and have been so for almost 10 years. 8 weeks ago I got a tiny blister on my heel. Then a tiny cut on my other leg. Both became infected - So I got the right treatment, yet despite this I still have open sores that are three times the size of the original which hurt dreadfully. The nurse has dressed then weekly with hydro colloid plasters ( like compeed plasters) and now I seem to be becoming allergic to them as the skin around the area has become red and painful. They have checked for diabetes and blood pressure in my limbs all of which are fine. Any other ideas as to what I can do or anyone who found a solution for these leg ulcers?
