Crazy.
I mean it was just last week that I was walking around in pain because my right groin was hurting when I would walk, or move my leg in a certain direction (usually pulling it sideways inward). It only lasts a day or two - especially if I buckle down and literally go "work it out". It hurts a tiny bit during the workout, but I press through it. The next day - you of course feel some soreness from the workout itself, and it begins to mask the aching. By day 2, the aching itself has noticeably subsided, and by day 3 its gone.
My very first days of BFS I had a very swollen (not just achy) right groin gland. Before all the twitching started.
You and I are not the only ones. As you know, 7 months prior to my BFS starting, I was put on AZT (zidovidune). You may be familiar with this drug from the movie "Dallas Buyers Club". If you haven't seen it yet, I would encourage you to. It really goes in to how dangerous and poisonous this medication is, and all the people who died from taking it. Because of this, I and a few others who were put on HIV Post Exposure Prophylaxis have found eachother online. All of them ended up with BFS. One ended up with Sarcoidosis. A few others ended up with Guillane Barre Syndrome. But all of them went through a period of neurological symptoms and twitching.
My point? These folks also deal with these strange gland "aches". None of us can feel the glands swollen. But movement hurts. It feels like a "pulling" and "pinching" feeling when you move. At first it was my armpits and ribcage. Now the pulling/pinching is in the groin (if it happens at all). My armpits will flare up a little bit from time to time, but nothing painful. Mostly makes me itch my armpits a lot to relieve the weird sensation Im having.
This type of reaction absolutely comes on after I "fall off the wagon" diet-wise. Especially sugar. I have a major sweet tooth. I can't go very long without oreos, or chocolate chip cookies, or ice cream, or maybe a wendy's meal (with a soda). I am fine with one-off events. But if I fall off the wagon, the inflammation throughout my body increases for sure. I read an article last week about inflammation and exercise. Studies were done showing that mild exercise (which must include both weights and cardio) reduced inflammatory immune activity by 30% in otherwise obese, sedentary people. And these folks barely worked out. We're talking maybe some walking. Maybe some pink dumbbells. Maybe some minor exertion. 30% reduction in various "IL" immune markers that were associated with inflammation.
Exercise works. I can't live without it now.
My eyes have been on Lymphoma lately because of this. But I know at least 2 people who were diagnosed with Lymphoma who both beat it completely (disease free for 10+ years) with dietary changes and exercise alone. It makes me feel like we (or just I) have a runaway inflammatory immune condition. I truly truly truly feel on a day by day , minute by minute basis that I need to constantly knock down my immune system a bit with constructive stressors like exercise.
If I don't, I can honestly feel it creeping up on me, throughout my whole body. Its a very unnerving, scary, and weird feeling. I feel it the worst when I first wake up in the morning and im still laying in bed. I wouldn't say its a crawling sensation. But its moreso a strange vibrating/tingling/inflammation feeling that saturates all the muscles in my body. Mind you - its just subtle. Its not like im sitting there vibrating or anything.
Its the most subtle, annoying feeling of whole body "agitation". That's a good word for it. I feel a bone-deep agitation throughout my whole body. And the only way to get rid of it, is to literally "Flex" it out.
So my workout then. In summary: exert every muscle group with isolated weights/machines. Then get on the treadmill and exert your lungs, diaphragm, heart, and subsequently, your brain.
With the muscle groups, use the weight that is slightly difficult for you to hit 10 with. Only slightly. You can totally do 10, but it takes a bit of effort. Only go higher in subsequent workout days.
1) Dumbbell fly's (shoulder workout, bringing them out to the sides)
2) Dumbbell fronts (shoulder workout, bringing them out in front of you alternating arms)
3) Dumbbell press (shoulder workout, pushing dumbbells above your head, palms forward)
4) Bench press (chest)
5) Incline press (upper chest)
6) Machine fly's (pulls arms together in front, squeezing chest muscles together)
7) That machine where you sit and push your shins up, working out your front thighs

That machine where you are on your stomach, doing the same thing working out your rear thighs
9) The machine where you pull the bar down while sitting, works your whole back
10) The machine where you're sitting upright and pulling back (like rowing)
11) Situps of some kind
I also do something I saw on P90x ... which is lifting my knees out to the side, hitting my hands which are hovering about waist high. This stretches the lymps in the groin pretty good. Then doing the same with knees coming up in front of me too. maybe 10 or 20 times. Don't overdo it.
Then I get on the treadmill. Incline 5.0 ... speed 3.0 .... and I just walk. Usually I only do 5 or 10 minutes. Sometimes i do 5 minutes and run for a minute (speed 5.0), then walk for a minute, etc.
The key here is breathing as deep as possible and exhaling deliberately the whole time. This is *Huuuuuge* for calming my lungs, and whole chest cavity, which often feels agitated and inflamed.
Then I rest. I rest as long as my body tells me to rest. 1 day, 2 days, whatever. I can always feel it creeping up on me again and I know when I need to work out again. I try not to let it get that far. Usually resting 1 to 2 full days is all I need.
As the iterations continue, I can increase weight. And as I get more confident, I begin to do "Chest Day" then "Back Day" ... on these days I will do max weight 7 reps ... and do four sets on each exercise. So really working out the muscle groups. Then the next week I will switch back to the above-described sort of "Circuit" workout, doing whole body. I find benefits health-wise from doing both, alternating.
The real key is to make sure I get enough sleep. Since my New Years debauchery, my sleep disorder has returned, and I always wake up at 5-6am after only 6 hours of sleep. This leaves me exhausted all day, and inflammation goes up big time. I have found that if I push it harder on the treadmill, I can make my body tired (in a good way) enough to get some better sleep.
Again, without the exercise, I can't even function sleep-wise. It just seems to fix everything. All the time. I wish I knew what was happening. .... inside me.
