dear friend, welcome to HCM.
if it is not worsening and you have no other symptoms (like fever, wheeze, breathlessness, increasing swelling/redness
, palpitations , weakness, discoloration around the bite) , you need not rush.
but be watchful. only mild allergy
would give you raised weals, itching and pain. could take an allegra
120 mg or cetrizine
keep me posted.
