Hi first time posting

Hey I'm 39 female and I would say I'm pretty fit and well.  So I've had a lump on back of neck in the hair line which has a red mark around it.  I mentioned it last feb to my drs as I was having night sweats and severe headaches but I was also really stressed because of work which the dr said I had sever anxiety and was castastrophing things nd the lump could be caused by stress.  I ended up having 3 months off work for anxiety I was referred to mental health team and I returned back to work feeling really good as I was taking anti depressants but throughout all last year I suffered horrendous headaches and I had my bloods done two times and all came back normal I even ended up at the hospital one day because I felt extremely weak on my left side and so so exhausted but they did ecg and hoood tests and again everything was ok.  FST forward to this week the lump on my neck was really big and my mam told me to go get it looked at again and because I was having problems hearing out of my left ear. I was seen who will syringe my ears in two weeks if the sodium oxide she has told me to use didn't work. But with the lump she wasn't sure what it was and got the dr to look and the dr felt and said she wasn't sure and for me not worry but that if it doesn't go away in two weeks to go back and she would send me for a scan or if it changed size within the two weeks.  I'm just starting to think it's all connected as the night sweats have started back up again.  Thanks in arance
