I went to the doctor's a few months back in regards to a lump in my armpit. They told me it was not nothing to worry about and wasn't concern. I went back last week and the doctor found a 0.05cm lump.

I went privately to find they have found a 1cm lump in my axilla. They think it is lipoma but I have a scan next week again to see. Is it something I need to be worried about, ? Will they do further test to see what the lump is and if it is lipoma or worse ?

I have been experiencing shoulder pain and to collar bone. Sometimes a tingling sensation down my arm. It can feel like a nerve pain or shooting pain. My shoulder feels like I hit my funny bone in a weird way. It's not constant but it comes and goes. It feels heavy like I've done weights for a week straight. I feel tired all the time and in the nights nothing major but get hot sweats and feel weirdly lightheaded sometimes. It comes and goes.

My lump, it feels like I can feel it and In my way, when my arm touches the side of my chest /belly When I touch it , it's solid but it can move a bit. I'm just very worried and unsure.

I do have a scan , if that helps.

Thanks
