[|Human|] My son has warm lumps on the lower part of his legs that just popped up sometime today he just received his 4yr. shots two weeks ago and has been having reactions to them since should I go to the er now or wait and take him to the doctors in the morning?
[|AI|]  Hi! Good evening. I am Chat Doctor answering your query. These lumps could also be due to allergic manifestations. However, if these lumps increase or become painful, you might have to take advice from the ER now, otherwise you could wait and watch for the present, and give him an anti-histaminic Chat Doctor.  You could also apply lotion calamine on these lumps for a soothing effect. I hope this information would help you in discussing with your family physician/treating doctor in further management of your sons' problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish your son an early recovery. Chat Doctor.
