To just want the strongest possible drugs?

111?
my area has weekend and evening out of hours GP appointments

as pp recommended, antihistamine to aid sleep - original nytol (not the non drowsy herbal one)

What has the gp based the diagnosis on, did you injure yourself, got sudden burning pain, what bought it on, you need an xray, plus an mri, I had this and it was impingement that needed surgery, it was the physio who suggested it, the gp wasn't at all thorough, I had diazepam and cocodomol but gp are reluctant to prescribe those now. Tbh if the pain is that bad and you can't really move that arm I'd go to minor injuries or a&e to actually get a diagnosis.

I've had two frozen shoulders (at different times). With the second one I had the steroid injection, which was done by the physio and it took away about 80% of the pain. I'd recommend that.

Frozen shoulder has a progression of three stages to go through, but does get better eventually. The process for me both times was about two years.

My sympathies. It is very painful and it will be hard with very small children.

PS They told me it would take 2-3 months to return to normal.

If it is an injury, have you had an X-ray (did your GP request one)? Are you using a sling? I found this very helpful after I injured mine by falling directly on it (it eased the weight on my injured shoulder). I did go to A&E for an X-ray, as I was worried I couldn't use my arm properly and wouldn't be able to work and maybe had fractured a bone. Nothing broken but a lot of ligament/soft tissue injury and they were very helpful. (It was Covid time and A&E was virtually empty mid morning - I was seen in Minor Injuries). It was very painful and as I am not allowed to take NSAIDs (other medical condition) I could only take paracetamol. The sling support during the day did seem to make the shoulder easier than before all day and then less bad than before at night.

Buy some solpadeine max or nurofen plus. They're the strongest you can get OTC.
And tell the GP the pain relief isn't working and you need something stronger, like cocodamol.

I dislocated my shoulder and all the muscles around my shoulder blade went into a deep spasm. I had to sleep upright in a chair as I couldnt lay down. At one point I was sweating in pain. Only thing that worked were prescription strength painkillers alternated with anti-inflammatories, but also two of those stick on heat packs along the length of my shoulder blade. I had to rest my arm on a pillow as well.
Once the muscles had come out of spasm it was so much easier. Physio was impossible until they happened. Id rather have babies without any meds than go through that again.

Why a private one? My GP prescribes me 30/500 cocodamol for pain. Speak to the GP OP.

Re the physio not offering physiotherapist, could you afford to see a private physio? I did for shoulder impingement and they did deep tissue massage, manipulation and something involving a heat wand and it offered very good relief for a few days. The NHS physio, when the appointment came around, was just exercises, which to be fair after several months of doing them, seem to have sorted the problem but the private physio was a very good short term fix. NHS don’t in my experience offer anything hands on as they don’t have time in the appointments. My physio barely touched my shoulder.

Phone 111 and get some Zapain. I am in a similar boat so you really have my sympathy. Chronic pain is a nightmare.

If you can afford it, get a private prescription for codeine. Could it be s trapped nerve? I had that once and my brain was telling me my arm was in a mangle being continuously squeezed, all a false message of course but it was the most painful thing ever.

one other thing that helped me. I had to sleep in my back as it was too painful to sleep on either side. Put a pillow under the painful arm to support it so the shoulder is as straight and supported as possible, that way it limits any movement.

I hear you, frozen shoulder sucks big time. The pain will reduce but while it’s acute it’s horrible. I took ibuprofen and paracetamol concurrently but it was still very difficult if I’m honest. I paid privately for a steroid injection and that worked.

You posted about this earlier.

I agree with you OP - I can’t take NSAID due to my asthma and paracetamol doesn’t cut it.

I recently fell and hurt my back, Paracetamol and Ibuprofen weren't helping so tried co-codamol but my pharmacist was very anti, anyway they gave me constipation which is not ideal when your in pain. Different pharmacist recommended Nuromol, they were fab and you take them every six hours, they start to work straight away, that and a hot water bottle got me through the first few days.

I agree with those saying co-codamol is worth a try.

Pain relief is a step by step thing, GP’s are under a lot of pressure now to do it this way and giving out the really strong stuff is an absolute last resort after everything else has failed really.

I had some type of frozen shoulder years ago. Had it for months, GP prescribed anxicalm as a muscle relaxant. It might help if you are having spasms.
I had codipar for back injury where my back kept going into painful spasms

Paramol - you can take it with naproxen

What strength naproxen have they given you?
is it muscle spasms? Honestly heat is often the best thing to relax spasms.
I have a nerve issues in my shoulder and that triggers muscles spasms at times. Things which work for me are finding pressure points on my shoulder that are tender and pressing them until the pain subsides - hurts like hell for about 30 seconds then starts to ease.
I also find lying on my front with my shoulder supported by a pillow. Arm bent behind my back. Sort of forcing it into a shoulders back position. Slept like that for years as it was the only way I could stay comfortable.

Meds wise Naproxen - check what strength you’re taking. It takes a bit longer to really kick in than ibuprofen as it’s usually a longer lasting med (12hrs) make sure you take it with food.
Co-codamol.
But overwhelmingly keeping it warm was the best hot packs whenever possible. And keep it moving

Ask your GP for some muscle relaxants. If that combined with naproxen and paracetamol doesnt work then go back and ask for something like gabapentin which works on nerve pain

what does the gp think you have done to cause the pain?

I went to a pharmacy to get the strongest pain relief I could when I had toothache. Solpadeine actually had a little more codeine in than non-prescription cocodamol.

Did you actually injure your arm/shoulder or not?

If not it could be frozen shoulder, gps in my experience are woefully unaware of the extremeness of the pain and how utterly soul-destroying it can be, especially at night. I ended up on oramorphe at bedtime for mine.
