I would try with a rheumatologist, or neurologist. Most primary care won't take it seriously. Hope this helps. I am where you are, only now I have docs that are helping me
They wont listen to you , my advice is to go to a homeopathic doctor or physical therapist. I keep walking into a wall when I tell them anything concerning my back pain or joint pain. The Osteopath has helped me get over the back problems. Joint pain can becaused by rehumatisim. You need to take fish oil or eat smoked salmon or mackrel. Very good to eat in the morning that will help releive the joint pain. Good luck!
God Bless
