The discovery of a small lump & several swellings on my right neck, head & ear

7 October 2010:

Morning: Discover a small lump on the bottom of my right neck (on shoulder)
Evening: Went to see doctor (GP), notice another swelling on the back of my right ear & some small swellings around the back of my head(right side only)
              Dr. said it might due to viral infections & prescribed me with medicines - antibiotic, for swellings & Multivitamin.....taken the medicine for 4 days...no signs of improvements - seems like more swellings appear

11 October 2010:

Morning:  Complete my last course of antibiotics, not much improvement
Evening:   Went to see doctor again(same one) - he prescribed another course of antibiotic, swelling & Vitamin C.  I asked him could it be due to heatiness?  Coz I've been travelling & might not drink enough water & the last month have been a hectic month for me with lack of sleep etc.  He said maybe & asked me to monitor my situation for another week.....drink at least 3 litres of water/day, eat more fruits & vege & cut-off red meat....If my condition did not improve, I have to see a skin specialist....

Question is should I wait for another week?  Should I consult skin specialist or other specialist?  Could it be due to long hours of mobile phone usage???  I want to be remain positive..... but somehow I will always think of some worst scenario?  It's scary la.......And can't seem to focus on doing anything....that's why I must write down & keep this like a logbook for me....
