I suffered extreme itching while trying to sleep and awakened with welts on back of neck and waistline. I had eaten very spicy Indian food a few hours earlier. Early today my upper lip swelled up on one side and has stayed swollen for several hours. I have applied cold compress to the lip. Could this be an allergy? I checked for bed bugs and there is no sign of them.
Hello, As you explain the history yes they are signs of allergic reaction probably due to the food you have consumed. Probably you need treatment with antihistamines. Please consult your doctor. Hope I have answered your query. Let me know if I can assist you further.  Take care
