Hi Mala,
I usually don't know what is the specific origin of the cause of my pain. I have been dealing with intermittent pain and TMS symptoms since my early teens so going on 30 years now and am sure that there have been a myriad of reasons at different times.
I think that nowadays, it often is has in its roots exhaustion and anger at not being able to just do what I want to do. I have 3 little kids and I decided to be a full-time stay-at-home mom, so almost all of the time, someone wants me or needs me. And that is pretty much at odds with my personality, which re-energizes with time by myself. And not too mention, I am no Martha Stewart and no fan of the kitchen, where I seem to spend most of my days. We have also moved to the suburbs for a better life for our kids (the typical - more space, more yard, less-expensive and good public schools) and most days, I long for my past city and career-oriented life, so there is definitely ongoing conflict for me with that. Combine all that with no time or energy (or desire!) to actually think about what is going on with me and I think it is inevitable for pain to emerge.
Pushing forward with some kind of activity - no matter how small - is really important for me, though. Last night, as an example, my stomach was really churning and hurting and I started to get fearful (a few years ago, I had incessant, incapacitating stomach aches for a year, which I eventually figured out was a TMS symptom for me). I wasn't feeling that great at all and could have just laid down on the couch, but instead, asked my husband if we could walk around outside the house and talk about what we needed to do for spring gardening (an activity that I love). It was a really small thing to do, but definitely manageable and I knew I could do it even with my upset tummy. And by the time we got back inside 15 minutes later, I realized my stomach ache had gone away and I felt completely fine again. The distraction is really helpful because otherwise I focus on the pain and fear and everything gets worse.
For some reason, though, I have to take the attitude that I am going to do something "in spite of the pain" and not try to distract myself for the purpose of getting rid of the pain. If I take the latter approach, it doesn't work. When I do the former, it is usually much more successful. If you have read Dr. Claire Weekes, it seems kind of in line with her describing accepting, rather than fighting your situation.
I hope something is helpful here. I feel like I have rambled quite a bit. Praying for relief of pain for you today!
