@melissahebert This is post 3, with prior ones in this forum - sorry - but I can't edit prior posts - so there is more information, below. I am not a Doctor so this is not a diagnosis. However, spasms, and pain in an area are generally part of myofascial pain. Medical Doctors are notoriously ignorant about muscuar pain and it's consequences. Nerves aren't necessarily always "entrapped" but rather compressed, irritated. This may repeat some of what I said but, you'll may want to google "trigger point massage" and look for stretches for all areas of your hip (both front and back) and do them. That being said, overdoing trigger point massage can cause some pain and often the "tension" is internal - and you have evidence of that. That's where the stretching and exercise can help for the internal (as well as the LA wand).
Also, I found working the stairclimber at gym as well as weights, pilates, TRX (I talked about that in my prior posts). I also use an inversion table as I have some degenerative disc disease. Supplements helped too, maybe, I am taking 1 tsp of hemp seed oil extract orally, resveratrol supplement + quercetin supplement and 1 carnitine seemed to help me, too (see Amazon). For exercise, stretching physical therapists and knowledgeable massage therapists were the most helpful. I finally found a certified massage therapist in the Palm Desert, CA area called MRT (muscle repair therapy) that does intense ultrasound and stretching - that helped me immensely but I had a history of doing tough martial arts including Judo with breakfalls on the legs / hips so some of my issues were due to scar tissue he's remodeling (and it's working). If you can take heat you can lay on jade stone far infra red heating mats, too - that heat penetrates (however, if nerves are irritated and that is the source of your pain it could get worse ((supplements can help that)). Check and see. I personally went away from ice because it tends to cause trigger points. However, I bet you'll find stretching and exercise (and very deep inspirations) will help you the most. Try stretching the piriformis and all kinds of other muscles and make sure you don't have weak muscles. Muscle imbalances as we get older can happen and a weak muscle is a tight muscle (i.e. "piriformis syndrome" - stretch it and do "clamshells" with some resistance bands). Glute spasms can be caused by piriformis syndrome (other tight muscles would cause spasms near the anus; TRX workouts will help with weak back and glutes and weak core). It's all connected but you can get it all to relax. It isn't permanent even if you've had it a long time - but, that being said, chronic pain gets harder to get rid of the longer it goes on. Books to read: Headache in the Pelvis, Life after pain (Kuttner) and Pain Free (Egoscue) - but I prefer more intense exercises than his simple e-cises ("A muscle that does not move becomes a muscle that can not move" -Egoscue). Also, "Heal Pelvic Pain" (Stein) is good. When you get nerve compression and possibly whole regions of tension - like I had. You may have tension you're not really aware of - you just feel the pain/ spasms/ other nerve pain (burning/tingling) and even other parasthesias (altered sensations also including sweating and ciruculatory effects). Good luck. Work hard and you can get your life back! I really suspect you just have myofascial pain in a region and it can be conquered. The Headache in the Pelvis authors point that out - everything in the hips and back is so tightly innervated together that often people have multiple problems that are related (i.e. back pain / hip pain / spasms / IBS, etc.). Those nerves are all connected. Free the nerves! That's a lot of info - and my last post, I should think, but that is what helped me after two long years to get rid of most of my pain in the lower back, glutes, sciatica, and ease IBS symptoms.
