Another doc, with different training and/or philosophies might just be the one you need? However, it depends on where you live...if this guy is the only game in town, it's rough. Go see a rheumatologist? Why not?
Besides, that can be cheaper in the long run than just 'going with the flow' and finding out much later [in my case too late] that the damages were doing.
Just NOW, before you even make another appt. elsewhere, ask for [or DEMAND] copies of your test results to date. Blood tests, MRI's the whole shebang. It may cost you about $.50 a page? But Then YOU have them for ever... And make copies for any other docs DO not ever give up your originals, they are precious. Still in all, new docs ALWAYS want to do the same tests over 'their way'. Each has different standards- and they all want a piece of the insurance pie. Sad but true fact of life.
As for treatments, some docs are in the dark ages and only prescribe neurontin/gaba... But, there are a whole slew of meds [OVER 50+] listed up in the 'stickies' as to what all has been tried and can be useful. Don't forget, each of US is different in what we can and can't tolerate.
I didn't do well on the neurontin...I was sleeping 14 hours a day and the neuro I changed from wanted to up my dose from 2400mg to MORE! I said NO way! Somehow? 5 hours of awake ness just isn't enuf to be HUMAN? Also, the hallucinations as a s/e were enuf for me? Changing neuros was the BEST thing that happened to me, two 'second opinions' essentially saved my life!
I hope this helps, you are early compared to me in my 'awakening' to other opinions? It took me 9 months [don't go there.....!] and I am ever grateful that my reason came thru and I got those 'opinions'!
Do NOT PANIC yet! Just go and seek the right guy you need!
