I went through this a couple of years ago in the same area. I found one of the very best doctors for this in the area. If you have any problems finding someone, PM me and I'll give you the info. You'll have to see whether she takes your insurance, if that's a concern.
The only thing I don't like is I have to pay the $25 co-pay in cash up front. But, she's awesome, and makes it soooo much easier than other experiences I've had over the past 20 years.
The Resource Center of Dallas also has (or had?) a free clinic they sponsor one night per month you can go to, if money is an issue. You'll have to call them for that, as I never went to it.
I don't know if either of these will do injections for you. I would think if you really need the iinjections done, then the Resource Center Clinic would be the best bet. Monthly Office visits to my doctor would likely be too expensive. I don't see why you can't do them yourself or switch to pills. I did them myself for a long time and then switched to pills. You have to take controll of this; it's for life.
