I was bit on the calve by a yellow fly and had no reaction for 24hours and then my calve swelled up look like my thigh by the time I made it to the ER My leg was so swollen that my toes were tingling and I was told by the doctor if you have a reaction right after the bite it is allergic and if you have reaction1-2days later it is infection caused by the bite. Only cured by antibiotics! And now 3days after the antibiotics the swelling is gone but the itching is unbearable!
