Should I get a tonsillectomy for recurrent tonsillitis that may not be caused by strep?

[geff_chang]

I am a 24-year old male of average build.I have recurrent tonsillitis (which has been going on and off for months starting October 2007),but it doesn't seem to be caused by bacteria,because Anti-Streptolysin O tests return negative(just recently, and a previous test months ago when I had another tonsillitis).I'm thinking my throat infections are viral in nature.Apart from that, I am also having colds.AND some unknown rashes that appear randomly;they may be allergies, but I've never had a history of allergy before.I understand tonsillectomy should be considered for recurrent tonsillitiscaused by strep. But what if it is viral?Would tonsillectomy help me in the future?I am worried a tonsillectomy may cause more harm to my immune system.What are your thoughts? Thank you.
