Hi.
Thanks for your query.
Noted the history related to your younger sister having problem with gases,
belching and on pressing and gets temporary relief. Got foot pain today, and got belching on pressing on the foot.
No, there can not be a gas in the foot. This acts on the principles of acupressure hence nothing to worry about gas in the foot.
I would suggest you the following for her since she has two problems:
1) The gases: the causes can be many, the commonest being:
Aerophagia due to stress and/or anxiety.
Intestinal chronic infection with imbalance between the good and the bad bacteria, the overgrowth of the gas producing bacteria can cause gases.
I would advise the following:
Reduce the stress and/or anxiety.
Stop the aerated drinks.
Home-made fresh foods only.
Tests of stool, blood.
If infection is present to give her a course of an antibiotic and
metronidazole along with activated charcoal and PPI like
Omeprazole.
This should solve her problems.
2) The pain in the foot:
Have a clinical examination and see if there is
tenosynovitis or so.
Orthopedic Surgeons opinion is the best to get an appropriate diagnosis and to get the proper investigations and treatment to get a relief.
