I have just discovered a lump under my armpit which has grown around 1 cm in size inside skin and painless , it has been there since like 8 months , so when i contracted covid 8 months back it swolled after some time it shrinked but not fully an now its size have increased i dont have any history of cancer but i am a big time hypochondriac even the thought of cancer has killed me , i consulted a local mbbs he said it is nothing , he didnt even aak some questions which made me rethink for second opinion , the lump is hard it does not move painless , i have not lost weight and my energy levels are fine the only thing i have was 5 jolts of cold within last two/three months , and i am literally depressed , i cant afford a md consultation right now , is this something thing common and nothing to worry or should i be worried as the size has increased , please help
