Medical break for a little while

I have been MIA for the past few weeks b/c of school and also medical issues.

I have been getting a lot of swollen lymph nodes in my groin area and my neck over the past 2 weeks. I am not sure what they are from but I am hoping it isn't too serious. I eventually felt a lump in my throat that comes and goes and I am guessing that is from my tonsils. I also experience occasional pressure in the ears. Because of this, I am on antibiotics since the doctor told me I may be fighting off a bacterial infection (even though I do not feel sick other than having the lump). I have been on the antibiotics since Monday afternoon and I haven't noticed any decrease in lymph node size. The lump has gone down a little bit but it is still there (it still comes and goes). The weird thing is that from the time I felt the swollen lymph nodes to the time I got the lump in the throat was 10 days. That is a very long incubation period (especially since tonsillitis has an incubation period of 2-4 days) and I am not sure if that is normal for something like what I am experiencing (or it may not be tonsillitis).

If the antibiotics don't get rid of the lump and swollen lymph nodes, the infection could be viral. Viral infections cannot be treated with medication so I would just have to wait it out. If it still doesn't go away, I will probably demand an ultrasound, CT scan or a biopsy to check for cancers like lymphoma. I know people who have had lymphoma and experienced no symptoms other than the swollen lymph nodes so I am getting a little bit nervous about that.

I have been debating back and forth on whether I should run through this or not. I know that running and exercising can improve lymphatic function but I am also afraid that it may make it worse (because of the increased stress exercise can put onto the body and stress can cause swollen lymph nodes). I don't know, maybe I will try to get back into it after I am done taking the antibiotics since nothing else is working.

Any thoughts about this? Am I overreacting or being a hypochondric?
