I have a lump over my left clavicle.It has been there for over a year and when I first noticed it I was having alot of neck pain and strain and I assumed it was due to that. It was soft at that time and not really painful but big enough to be noticeable by other people.I showed it to a Dr she felt of it and said it was a fatty tumour and nothing to worry about and I also had swollen glands. It has gotten alittle bit bigger since then and now it stays hard all the time and it causes some pain.I recently went to the ER with a Severe head ache pressure,blurred vision,neck sweating and stiffness,hearing disturbance,nausea,weakness,muscle spasms,chest pain,flutter sensation in ovary area and leg and thet did a cat scan of head and a spinal tap and it was okay and said it was a severe migraine,I went home and couldnt raise my head for the pain for 2 weeks I am better but I am still having head pressure headches severe weakness ,lightheaded etc...I was wondering if the lump could be related to whatever is going on with me know.I am 44,I have barretts esphagus which is okay right now.My mom had hasimotos thyroiditsis and thyroid cancer and cervical cancer..Any advice or help would be great,I dont have a Dr right now.Sorry so long!Thanks,Pattymac
