Hi there ~
I understand your concerns. I commend you for having stopped smoking
marijuana I also think that your having cough, foamy mucous, sharp pain
below shoulder blade are a matter of concern and may be related to your marijuana intake. I also believe that you may have a chest infection
, or pneumonia
) which is making you have these symptoms. I also believe that you should consult a local doctor to make sure that the medications you are taking are the right ones and to have other medications prescribed by the doctor, if the ones you are taking are not helping.
I hope this helps. Take care and have a lovely day!
