I think, you have not written your investigation result correctly. I assume that your HIV
tests are negative, FNAC is also negative.
The best thing is to do complete excision of the solid tumor
and send it for histo-pathology examination. FNAC has chances of false negative results. if any pus or white liquid should also send for Culture and sensitivity test.
Do you have that type of lumps any where else in your body, like in groins, axilla?
Is your spleen
There can be many more causes for these multiple bilateral lumps.
Any other associated symptoms, like fever
, loss of appetite, loss of weight?
it is better to reach to some confirmed diagnosis, which will help in proper treatment.
Wish you faster recovery.
