Suggest Treatment For Arthritis And Pain On The Temple

hi, I have a pain on my left temple that is very sharp once touched, my doctor said it could be a arthritis pain the the nerve, and I have had this headache pain for a few years.the doctor told me to have a teporo artery biopsy done. I take several meds a do to other medical conditions I have . they say my health is to bad to do surgery however I asked himwhat if they found something how would they treat it, he told me with more steroids on top of some I m taking now for other things. do you have any output in this pain I m feeling. it started out as a size of a pee and nnow ite about 2 inches in length, hasn t risen and higher just more spread out..but at touch it really hurts terrible and then after it goes up the side of my head to the top for a few minutes before it settles back in place. I notice that it has really bothered my eye condition and cant see as well as I use too.. my dr told me that if I don t have this biopsy done that I could go blind all together
