That sounds interesting DOG, I used a McTimmoney chiropractor with my 2 DCs and she was awesome, sounds vaguely similar, worth a short if you can find someone to show you how to do it.
I used to spend a lot of time on the breastfeeding boards and used to type what worked for my DS who had colic. I'll paste it below but it actually sounds gushing and patronising reading it back many months on. LOL so don't make fun of me people 
"My second child cried for 2 to 3 hours a night until aged 10 weeks, feeding didn?t seem to help or calm him and I felt like I was at my wits end, in fact I used to make the mistake when he screamed of thinking he was still hungry, so I?d try and feed him on top of the wind and then he?d scream harder and then do a massive burp and bring the feed up, so I spoke to my health visitor about it at the time and her tips to try were:
Warm bath covering tummy.
Lying him on his tummy with a warm (not hot) hot water bottle under him to soothe tummy.
Cycling his legs whilst he's on his back. Holding feet palm to palm and rocking legs sideways, whilst lying on floor or lap.
Or scooping with right hand down his right side whilst holding feet palm to palm.
Or rocking him face down well supported on legs.
She also said don't eat anything that gives you wind such as brocolli, cabbage, caffeine, cauliflower, garlic or other stimulants. However I don?t believe there is actually any evidence that what you eat affects your milk. Certainly Tiktok on mumsnet also I believe says this (from memory) however I hadn?t started posting properly on mumsnet at this point, so I gave it a try. She said if none of the above did work I could try buying Colief drops from a chemist and mixing in with a feed by expressing it first, as she said sometimes colic is caused by a lactose intolerance. I never needed to buy these in the end.
I found that out of all of those the cycling the legs was particularly good. I also found that as he had trouble burping, the infacol made him cry harder as it coalesced the bubbles into one big one that still went downwards but hurt more. But giving him gripe water after every feed straight away really soothed his tummy. I had to do it every feed though without fail.
The warm bath in a quiet room was also a real help. Every night at the time he started to get agitated I would put him in the bath, in a bath cradle and keep putting warm water on his tummy and every now and then top the bath up with warm water, so it wouldn't get too cold for him. Once or twice he was in the bath for 2 hours in the early days as it was really calming for him, my poor DD watched a lot of CBeebies in those 10 weeks, much to my shame, as he was a Winter baby too. Once he started doing big yawns and it was bedtime, I'd take him out into a dark bedroom and change him and BF him quietly and then often he'd go to sleep straight away. This was a huge relief after I discovered how much this worked for him. In the day I'd keep him up for only 90 mins only before putting back down for a nap and this also helped.
Remember things will get better soon lovely, sending you a very unmumsnetty hug. I found it so hard to see the wood from the trees at this stage. My tips may or may not work, as every baby is different but there?s my thoughts. There is some great advice on here though, I wish I?d used mumsnet when DS was tiny"
