I am not sure of the relationship of the hug and your infections? But for the MS hug I have tried several things. I am not one to turn to medication right off the bat. I plan to live a long time and try to keep medications i.e. pain killers or muscle relaxes.., as a last resort. Although they can provide various levels of relief, side effects, toxins, and organ damage run foremost in my mind.
My hugging runs from the bottom of my rib cage\top of abs, around my sides, to the middle of my back. I have found the primary cause to be weak latissimus dorsi and trapezius muscles. This causes my abs and intercostals (between ribs) to work over time and feels like I am being squeezed. Sometimes it squeezes so hard I have trouble eating.
Heating Pad: I lay on a large pad on low for 2 hrs when I go to bed. 90% of the time it relaxes the muscles by morning and feels better. Put it horizontally right bellow your shoulder blades.
Massage: I have my back rubbed, but also sides (under the arm to hip), intercostals (between 5th & 6th, 6th & 7th ribs), and the abs muscles under the rib cage. It feels a little weird, but helps a lot. This lasts me several days of relief, but gets pricey to do frequently.
Gua Sha: This is Chinese skin scrapping I learned first from my chiropractor and then research. It is easy to do, a little pain full, leaves what looks like bruises, but it stimulates the nerves, frees the muscles of old (toxic) blood and provides days of relief. My wife does it on me when I have Pain in my extremities and MS hug. For the hug, you do it in the same areas as the massage. The idea is you thin the muscles as you scrape the skin with a Gua Saw tool and lotion (china gel works best). This brings up stagnant blood and frees the muscle to better communicate. The Chinese see it as energy flow or chi. You can look it up on goggle.
Acupuncture: Acupuncture takes a few visits to kick in, and you must consistently go, but it can stimulate weaker or atrophied muscles to strengthen if electric stem is used. It also calms the nerves more long term.
Exercise: It is highly important to exercise those muscles, as this keeps the communication active and muscles working. You don’t want to lose what you have.
Hope this helps.
