First of all, stop scratching your bites! I know it’s difficult but if you continue doing so, the bites can get infected with bacteria that will enter your bloodstream and cause havoc on your body. Save yourself from nasty infections by leaving the area alone.
This one makes the first point easier to follow. Stop the itching with some cream or lotion. This will also reduce swelling and clean the area, decreasing the chance of getting those unwanted infections.
If cream or lotion doesn’t do it for you, there’s also antihistamine as tablets or liquid. You should contact your doctor before taking this. I would prefer that you use cream or lotion – it’s cheaper and works in most cases.
Use ice or cold water to soothe the itching. This also prevents or reduces swelling and inflammation.
