Lumps in both Armpits

Shanza
Hey ladies, 
A couple of days ago I realised I had sharp pains under both of my armpits. It hurts to have my arms by my sides and it also hurts to raise my arms. When checking to see if there was anything visibly wrong I could see that my armpits look bruised and when feeling the area I came across some lumps.
In my old country I had free healthcare however in my new country I don't. Is this something I should go to the doctor for or has anyone got an explanation or past experience? I've also been feeling super exhausted recently but I wouldn't say I've done more exercise than normal.
