I would suggest making a list of your symptoms with you when you go to see the doc. tomorrow. Since your doctor seems to be aloof you may be so anxious that you forget what you wanted to tell him. I know, have been there myself.
These symptoms really do need to be checked out. Try not to take his attitude too personal. Sometimes they are like that to all their patients
When you can do try to find a doctor who you are comfortable with. My family went to a general practice doc where I used to live and never really felt that he took me seriously, long story there. When we moved we had to change doctors and we are going to a great doctor now. It has been like night and day. There were some issues with the insurance and practice and we thought he wouldn't be in our network any longer, he is so good that we would have been gone to him even if we had to pay out of network!!! Thank God it worked out and we didn't have to go that route.
Hope you get to feeling better soon
