I Don't Really Know Where To Start Without Sounding Like

I don't really know where to start without sounding like a hypochondriac and I'm not sure if all symptoms are even related I've tried asking my husband to help me find a doctor or even listen to me but with everything going on he thinks I'm overwhelmed and it's all in my head. So I'll just start from the beginning. In my late teens I started noticing a small pimple like wart shaped lump on my stomach still there to this day than a couple yrs. later another and so on and so forth I'm 31 yrs old now and now have about 6 of these bumps(that I know of) threw out my 20s I've been sick more than the average person It seems like my son would come home from school with minor cold I end up with bronchitis and every yr it just gets worse I recently had my last child a yr ago and had a very hard pregnancy every month I was sick ( kidney infection,yeast infection,bronchitis again,itchy skin so bad I can sleep and wake up all scratched up and sometimes bleeding) It was just a nightmare and at this point I'm thinking something is really wrong with me! My daughter is now a yr old and I'm now noticing a new lump in my armpit and now I think my lymph node along my jaw line is a little swollen not to bad but enough to be uncomfortable when I turn my head and look down. Also since I was about 7mos pregnant I noticed I stared having hot flashes,night sweats,itchy skin thought maybe due to pregnancy hormones. A yr later still having these issues but now during the day as well as severe headaches, nausea, hot and cold flashes,dizziness(mostly when I stand up and move around)the dizziness anyways. this morning I had all of the above and I decided I would take my temperature while sweating and having hot flash and my temp was 96.6 I'm really starting to get scared here mostly because I've been keeping this to myself for yrs. now I finally tell my husband and he says he notices the bumps already but still thinks I'm just sick and getting myself all worked up but I swear I'm not sick (besides these symptoms I feel fine) I was not born with these bumps and every few yrs I get another he refuses to consider that there might be a problem and won't let me see a doctor can you please give me some kind of easy explanation as to what's going on with me so I can stop stressing that I have cancer or something worse Please help me I need peace of mind!
