Here you have told you are having this kind of thrombing back pain
on and off. And now it's more from one day. I suggest not to treat the symptom but take proper treatment for the cause.
Now to find out the cause you need to check with spinal MRI
of your back. And as per the report I suggest to consult orthopedic doctor take suggestion in treatment. It can be with medication and physiotherapy
to relax the muscles and reduce inflammation at painful soft tissue
. Or else if there is major issue with MRI report then ortho may suggest for surgical correction also.
In both above cases you need to follow up with physio for postural correction and advice as well spinal exercuses to improve strength and stamina of spine.
If there is no problem in MRI spine and after all if there is still pain in abdomen also then you need to check with ultrasound
of abdomen and as per report as well cause of pain need to follow up further treatment for it.
For this I suggest to consult your gynec and take proper suggestion and treatment.
Usually dull thrombing pain is usually related with spinal problem only. How ever the cinformation will be done by MRI of back only.
