1.5cm lump upper left breast and arm pit pain

I found a hard firm lump in my breast. Went to GP. She said she could feel a 1.5cm lump in my upper left breast.  She felt the other side and said she could feel similar in my right (I'm breastfeeding my 2.5 year old) she wasn't concerned and told me it could be a blocked duct and to make another appointment in two weeks time. I've had burning pain in my armpit/arm and wrist as well. (same side as lump)  (I can't feel any lump on my right side) 

 

I did this and had the telephone conversation today as the lump, arm pain and tingling is still here.

she has booked me in for a referral to the best clinic. I can't stop crying. I keep seeing the same results on Google and I'm scared to death. I have two young boys.  She said the referral may be delayed due to covid. 

 

No point to this post really but just to say hi and maybe here some experiences?

 

I feel so lost and alone
