First, you should be seeing a gyn.
Secondly, anti-depressants have many *approved* uses besides treating depression. The dosages used for treating other conditions is usually half or less than the typical starting dose for a major depressive episode. This is a well known clinical use for some of the SSRIs, SSNRIs, and the older tricyclic antidepressants. These medications at lower doses work on neurotransmitters that can be very effective in treating a variety of things, particularly pain.
I am not sure why you or your DH would be so against this. You are not being treated for depression, but for another approved use of the medication. And, depression is a medical condition, many people have it. What are you concerned about?
A few years ago (before you were on TE, I think), I was sick with what is probably some type of autoimmune issue. I went to 3 rheumatologists and 2 neurologists. The neurologist suggested I take a low dose of amyltriptiline, an older tricyclic antidepressant. I took a 10 mg dose (the normal staring dose for depression is 25 mg) for about 3 months and it totally made the issues go away. I knew there was a side effect of weight gain, and I was able to up my exercise, since I felt better. I stopped taking the meds and I never had to use it again. But, I would, if I started feeling really awful again.
You do not need to suffer. This is accepted medical practice.
