[|Human|] My 6 year old son has had a rash since this morning. Some spots are around a nickel in size. He has had this happen before, and we figured out it was a new detergent. However, this time, we haven t changed our detergent, and he has now said that it feels like pins and needles in his joints. We have been using Benadryl and Cortaid today to treat. He hasn t had a fever. Thanks for the help!
[|AI|]  Hi...sometimes an allergic reaction especially angioedema can cause joint pains and if there is no "itchy" skin rash and yet the kid is experiencing pins and needles sensation in the joints, we need to think about alternative diagnoses like connective tissue disorders.... I suggest you consult your pediatrician with this tip. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health. Regards -
