Hi, The elongated uvula can be due to many reasons: Local trauma by food, hot drink Allergy to anything causing angio-neurotic edema Fish and other sea foods are known to cause allergy Anything under the sun including the sun can cause allergy hence it is you and your husband who have to observe and notice the factors, foods, beverages that cause such a problem. The neck swelling may be due to reactive lymph node reaction. If he is not diabetic then oral steroids should also be given and kept ready along with antihistamine with him on his person all the time. Get the relevant blood tests done like IgE and so on. Once a cause is found he has to avoid these at any cost. Washed bowl with another preparation will not cause any problem, as it is not heard of till now, so do not worry. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
