I'm in charge of a makeshift hospital in one of the districts in Damascus. In fact it is difficult to describe it as a makeshift hospital, it lacks all the requirements for such a hospital. It does not have an operating theatre but only first aid stuff.

Originally I'm a dentist specialising in jaws and face surgery. I'm the only doctor in my district. Most of the doctors are either scared of the regime's oppression or have left the country.

I used to work in a government hospital and have my own clinic. In 2011, I was reported to the security for taking part in the protest against the regime. My clinic was stormed at 11 in the morning but thank God I was out. I had to abandon my clinic as well my home after it was raided and my father and two of my brothers were detained for a month.

The security told my father to phone me claiming that he had hit a man with his car and needed me to come, but he refused.

Since that time, I decide to devote myself to the revolution and establish the so-called "medical suitcase". I wanted to help the protesters who get shot at the demonstrations and cannot go to the hospital.

A young guy who was only 17 years old was shot in his leg a few months ago during one of the protests. The district was besieged by the security forces, the guy kept bleeding and we could not reach him till he died. His case was not that complicated but nobody could help.

So we started going to the places where the wounded are if they cannot come to us. Most of the wounded are scared to go to the government hospitals for fear of detention or killing. When I used to work in the government hospital it had turned to a military barracks, full of intelligence people.

I only work with a nursing staff. It's so difficult to find doctors – sometimes it takes us two days to find a surgeon who can operate on one of the cases or I have to take the wounded to his clinic by myself.

We had an orthopaedic doctor who used to help us, but he left for Jordan. Some of my colleague who are qualified in general surgery are in detention.

Sometimes we are lucky and can find a surgeon ... but it depends on the case itself – whether [the wound] is in the chest or the abdomen – in addition to the security situation.

In the beginning I sat up my hospital in a mosque but it was targeted by the Syrian army when they stormed the district. We were forced to move to one of the houses where we work secretly.

If there is a heavy presence of Syrian forces it is difficult to move the wounded – they will be stopped by the security. We ourselves cannot go to areas where there are many security forces.

I did an operation on a wounded man yesterday at one o'clock in the morning. He had already had surgery in his abdomen but the wound was infected. We smuggled him in and right after the operation we brought him back. We were worried the security would recognise him.

I also coordinate with other organisations to get medical supplies. We do not have that good support when it comes to the number of the doctors who work with and outside support. All I get is promises that I will receive a help but nothing so far. I do not have the most simple equipment a doctor need like a monitor or sterilisation machine. I gathered my medical supply from different places.

Either I do a "medical suitcase", which means I take my bag with me and go to the wounded, or I set up a makeshift hospital somewhere to receive the wounded and stitch their wounds or provide first aid to stabilise their condition.

For a year now, I have been asking for basic medical equipment from people who are abroad, but all I get is promises. I need a portable X-ray machine cause many of the cases are injured limbs.

Most of the limb injuries which do not hit the an artery, like broken bones, I can deal with. I can stop the bleeding and give the wounded antibiotics and painkillers. I save their life with what I have. I cannot treat injuries in the chest and abdomen – they need surgical intervention in a theatre.

I receive lots of people injured by mortar shells. I have today a case of a family whose flat was hit by a mortars shell, the parents were killed at once, but the two female kids were wounded. I treated one of them, but her sister died soon afterwards.
