Hello mate.
I have made progress. I have spoken to a doctor who is certain I have torn the tendon in my elbow. He prescribed some really strong anti inflammatorys called 'Peroxicam Betadex'. These are for people who have severe arthritus! I took these along with 'Omeprazole' tablets which combat the side effects of stomach pain and rashes (I didnt get any of these).
I took one of these tablets a day for about 3 weeks along with complete rest and the problem has really improved. It is not completely better but I can hit pads etc and have no problems.
Hope this helps.
