Brief Answer:
slings are pretty notorious

Detailed Answer:
for being associated with pelvic pain. The mechanism is not well worked out. But judging by the number of ads for lawyers handling cases on pelvic mesh, there must be quite a number of women with this issue.

I cannot make a particular judgement on your particular case without an examination. In an examination for pain. Bacially you try to produce the pain and that tells where it is coming from. Today, first patient, had chest pain that poking in his rib joints triggered. Not the heart. Likewise the main test for someone with lower limb pain would be if tugging the leg straight out triggered a line of pain going down the back of the leg (sciatic nerve) or if moving the leg out to the side triggered hip pain (hip arthritis). Or if bouncing on the legs produced lower abdomen pain (pelvic pain .. associated with mesh).

Brief Answer:
and... here's the bad news....

Detailed Answer:
all the options for it are bad unless it is hip (bouncing also will trigger hip pain in arthritis, but so will moving the hip and mostly... the pain is in the hip not the pelvis if it is the hip....so.....back to pelvic pain):

removal/surgical revision of the mesh: this includes changing adhesions... well known as a sucker's bet since the adhesions reform and more surgery causes more disruption and likely more pain.

Narcotics: somewhat effective on the pain but only somewhat. This isn't their best situation for treatment (deep bone pain from cancer narcotics do a great job for; tooth pain they are lousy for, this is intermediate but generally people have a minimal improvment on lifestyle).

coping therapy. Your best bet but still pretty awful. First let us start with several things you know. Pain in one spot will overwhelm the feeling of pain in other spots. Vigorously moving the hand after the hammer hits it blocks the pain somewhat. Unexpected pain or unexpected pain that you are not sure if it is going to kill you causes the most distress which is separable from the pain per se.
So.... taking control of the pain through doing things that are, well.,, painful is probably your best bet. Graded physical therapy, graded yoga (starting off slowly and working up to really painful things). Lowering pain feels good. The standard charts on this are in error when compared to the actual experimental data--the pain charts assume there is a zero in pain when you can feel good which is in the opposite direction of pain. The narcotic pleasure charts stop at zero and assume there is no pain in the negative. The experiments clearly show that it is movement away from pain and into pleasure that is rewarding and you can just as easily train a rat with giving narcotics and with giving pain (and then lowering it as the reward). So... doing a thing that causes pain (but not damage... it has to be supervised) in a therapeutic context and then removing the pain, feels good and can be linked to being more active in life (physical and occupational therapy, but also hobbies, activities, job, family, church activities, doing things, etc.)
