This is to inform, I have regarding complaints of Lower Immunity and getting frequent Cold, Cough, I was tested for Immunoglobulin levels (IgG, IgA and IgE-total) after which doctor prescribed the medicine KETASMA for 15days. I am a patient of IBS and taking Providac and Librax.       But Sir, as I started taking KETASMA (from 16-March-2011) and after 2days, I felt some swelling on the right side of my neck just below the Chin between the ear and the throat. Initially I thought it may be due to the climatic change or any other infection and I continued taking KETASMA. But the swelling grew more and after eating lunch or dinner I feel severe pain which is unbearable especially during the night time. There is no fever associated with it. So I went to my family doctor who is a Homeopath, just few days back. He told me that my Parotid Gland has swollen more and gave me some medicines. The swelling is now less but after eating the gland swells and gives more pain.      Sir, I have stopped KETASMA presently. So kindly suggest medicines to be taken for the Parotid Gland problem as the pain is seriously unbearable.
