You should go for fine needle aspiration cytology.
Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern.
Based on your description, this swelling seems more likely to be an enlarged lymph node. However possibility of pulled muscle or other musculoskeletal condition cannot be ruled out especially if you sustained an injury and its hurting you. Further sometimes post nasal drip leads to ear, nose and throat inflammation which can produce reactive lymph node enlargements.
A physical examination, ultrasound examination and fine needle aspiration cytology or biopsy is the means to confirm the nature of this swelling and whether or not it is related to a cancer. But if you are unable to see a doctor, you could try anti inflammatory pain medications for a few days. Antibiotic drugs may benefit you if there are clinical feature of infection. Reactive lymphnode or pulled muscle might settle down with this trial. If the lump persist, I insist you see your treating doctor and plan for fine needle aspiration cytology or biopsy once. You may have lymphoma, metastatic carcinoma from breast or some other lymph node pathology.
Continue with all other medicines you are taking.
