Swelling and allergy. With this email.

During the last 15 days, I have developed a swelling on upper right side of my neck, mildly painful when I press it. I had developed the same swelling 25 years back, at that time I took homeopathic medicines & it eventually subsided. Present day I consulted two doctors : First doctor said it might be a "sebacious cyst" and gave "lizolid" , "signoflam", "torkast" tablets along with two blood tests (CBC, IgE). The second doctor gave some diagnostic tests (CBC, ESR, Sugar Fasting, LFT, USG of the swelling, F.N.A.C. of swelling), along with "azithromycin" , "torkast" tablets. Yet to undergo F.N.A.C., as I am apprehensive that it may aggravate the swelling as it involves insertion of needle. I am highly allergic to cold, temperature changes, dust and eggs (sometimes my face & other parts swell up & itch after eating eggs). I exercise regularly & have been taking whey protein supplements for the last 6 years, eat dry fruits and nuts. I am attaching all my reports with this email.
