Thanks for providing more information.
Well as you have recurrent swelling,rash on ankle and calf so possible causes may include Stasis dermatitis,Venous insufficiency,Deep vein thrombosis.
In my opinion,you shouldn't ignore your symptoms and a clinical examination by your regular doctor should be considered ASAP.
If you leave it untreated then it can be dangerous.
Also avoid prolonged hours of sitting or standing in same positions.
Elevate your legs.
Apply OTC 1% hydrocortisone cream mixed with Bacitracin.
And take OTC Motrin and Claritin.
Further color doppler study of lower limb should be advised.
