How much can one person suffer? Terrible pain in right shoulder from straining. If I don't strain or hold on to toilet rim so I don't faint..I can't produce anything. I'm 56. Sphincter muscle too weak I think. Strain even when I'm on stool softeners. Fiber does nothing but makes it harder to go..heavier "bulked up" bowel movements from fiber just too much of an ordeal..feels like I'm on toilet forever straining and straining. Ugh. 😳 I have been in constant pain since stopping prescribed opiates cold turkey after seven years for degenerative back disease from bad fall at horse show when 21. Could eat pizza, tacos, hoagies anything no IBS, cramping or pain. Constipation yes, but I'm already constipated, but at least no more fear to eat and pain. Just put on vitamin B12 500mcg. It's tearing up my stomach. Side pain so bad I'm doubled over. I am done. Back on prescribed pain meds, will make an appointment, if they will take me back..who wants to live with pain and IBS forever and fear of eating? It's no life. 😣😪. Thank you for listening. I'm at my wits end..
