my submandibular gland first got swollen in july of last year i went to the doctor and he wanted to do a biopsy but there was nothin to biopsy so that was cancel. the swelling lasted for about 2 months and went away. it came back in january and lasted for about a month and again in may. m doctor told me that it might be a abcess did'nt give me any medication. i took a cbc and the only abnormal was Eosinophils and Mean corpuscular volume (MCV. it is now swollen again but it;s not that noticeable, i also had little skin rashes all over my body there small little dots. does this sound like hiv or alergies.
