Hello,
As you have not mentioned lower left side of which part, I'm assuming it as lower left side of abdomen. The following are few probable causes of lower left side of abdomen:
1) Irritable bowel syndrome
2) Inflammatory bowel syndrome
3) Ischemic colitis
4) Mesenteric adenitis
5) Urinary stones
6) Hernia
My recommendations are as follows:
1) Wait and see if it reduces by itself.
2) If it increases, give tab.
Buscopan and wait for it to subside
3) If it doesn't subside even after taking tablet, please do
consult a gastroenterologist.
4) Then you need to be further evaluated for other causes of pain.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
