Welcome to HCM
Red spots on leg could be due to many things . For example Insect bites
, Fungal Infection
, Bacterial infection , Mild bleeding into the skin , Drug Reaction . It would be better if you can upload a picture of it so that I can tell you what it is .
As of your headache and vomiting
is concerned Migraine fits
to the diagnosis , but with migraine medicines it should go . Kindly let me know what Medications were prescribed for you . SO that if needed I will change the medications .
