Thanks for the input.
Seems like you have Stasis Dermatitis, formed by the pooling of the impure blood around the ankle. The area above the ankle has the least blood supply in the body and hence is more irritable and prone for damage. Chronic stasis of the venous bloodseeping underneath the skin produces eczematous changes in this area.
The lack of pumping action of the calf muscles due to prolonged inactivity is a contributing factor.
If the rash is oozing, you can apply a moderate steroid plus antibiotic cream for 3-5 days under antibiotic cover. Also take an antihistamine like Cetrizine 1 at night. Do not apply the steroid cream for more duration, just to dry up the rash. Once the redness is reduced, apply a thin coating of moisturizers like Stelatria(Mustela) twice daily.
Prevention involves using Cotton elastic bandages starting from the base of the toes up with gradually diminishing pressure. Still you may get recurrences and may also require short courses of oral steroids to control the acute flare ups.
Also while you sit, keep the legs raised up fow a few minutes every hour and also flex your ankles intermitently to pump up the pooled venous blood.
You can get the following:
Hope this helps.
