hi there. My 19 year old son has little red welt like spots ( dime size ) on the palms of his hands. not a bunch..like 3 or 4 on each hand. also his fingertips are very tender, 2 fingers on one hand and 1 finger on the other hand. I am completely baffled....It has been like this all day. I told him that if it is still bothering him tomorrow, I would take him to see the doctor. however he seems pretty upset and worried about it. Can you give me an idea as to what may be the cause of these strange symptoms? Thank you for your time
Thank you for following up. We should differentiate allergic, fungal diseases, avitaminosis.  You should take your son to dermatologist and get him examined especially to rule out fungal infection.  Antihistamines(Allegra) can be given for night daily during 5-7 days.  Start to following antiallergenic diet, avoid chocolate, strawberries, nuts, tomato soup, seafood, market juices, oranges.  Take care!  Chat Doctor.
