Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. There is no need to worry for the lymph nodes but you have to take the drugs which I am going to prescribes you below. Your Benadryl is right in content, there is also a need to add steroid in the regimen this will suppress the allergic reaction caused by sting. You can also take antibiotics if you are suspecting of having infection due to sting. Please maintain good hygiene over the bite area you can so this by frequent cleaning and dressing. Betadine and dettol can be used for dressing and polysporin ointment can be used for applying over the wound. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
