Please I need urgent help from u my friends
First I have been having strange feeling under my armpit for a year now. Sometimes it's pain, other time it's just a heavy feeling .. The pain sometimes affect my left breast and heart area and my left arm feels heavy and uncomfortable .. In addition to dizziness and a whole host of other symptoms ( will list it if u think this is necessary )

Two EKG were normal and I did mammogram thinking of breast cancer and was normal a year ago( will repeat it again soon )

My question is: did u experience such strange feeling in your left armpit area and heart area ? Especially the uncomfortable feeling in left arm and armpit ( similar to feeling when u wear tight bra under ur armpit)

Is this Lyme or coinfection .. Which one ??

I am seeing cardiologist next week so what test I should ask for as Lyme patient ?

I need the most accurate, least expensive one cause I am on limited budget ?

What should I ask him to do in order to rule out carditis ..How can he rule out this ..which is something I am very scared of? Should I see different specialty for my case ?

MY llmd scared me to death more because he said its unusual symptoms with his patients ? Does that mean he is not educated enough ?

Do you think your lymph nodes are swollen? Mine always get like that and it's from Bartonella. It's very painful.

I know that no one is medically trained in here; otherwise I would have not gone to see doctors :)
however,  I am here to ask for support and advice from people who have been there in my shoes (something medical fields truly don't understand).
I hope someone can help me with my questions from experience please

To my knowledge, no one here is medically trained, and even if we were, we could not give you medical advice.  That he said your symptoms are unusual does not necessarily mean he is not educated.  If you are not comfortable with the next steps in your relationship with that MD, then I would consider seeking a second opinion from another MD in network or outside it.
