Suggest Treatment For Unbearable Itch On Body

have had an unbearable itch that usually happens in the evenings/nights (sometimes day time but mostly night) so I just googled it cause it's really irritating how it happens every night!!! Google results pointed me to Hodgkins Lymphoma, so I read it and realised that a have a small (pea sized) firm lump in my underarm, for the past month I have woke up about 3 nights a week dripping in sweat. I haven't lost weight though. I have 3 'lumps' on my cervix which only 1 was present after the birth of my 4th child 16 months ago, the further 2 developed in the last apx 6 months. I have what appears to be a large ulcer (very painful) on the bit of skin in the middle of my bottom lip which looks just like a pea sized hole for about 4 days now, my whole lip is agony. I bruise without cause, red/violet in colour mainly on the back of my calfs will appear and take about 3 weeks to disappear. I get headaches at least 4/5 days a week, the last one ended up a migrane after 10 consecutive days. Thread veins have recently appeared on my outer thighs in quite concentrated areas. I am 26, need to lose about 50lb, I quit my 5 a day smoking habit today due to this ulcer, I very rarely drink and when I do it's never more than apx 4 units of alcohol. I have no faith in visiting my GP (I have changed a couple of time due to moving house but they are all the same) - they didn't spot numerous cancers in a relative who was so advanced that she died 9 weeks later, appendicitis in my husband who almost died, didn't treat me for a kidney infection until I visited 3 times and demanded tests. I am not a hypochondriac, I just have no faith in GP practices in the UK so hardly go and end up in the situation I am in, they will never listen to all these issues! A lot? I know, sorry! Please help!
