The Spaniard has been suffering from an 'arm pump' problem which sees blood collect in the forearm and compresses the nerves, resulting in a loss of feeling from the arm through the hand.
Despite finishing sixth in Sunday's race, Pedrosa revealed that he started losing the feeling in his right arm once again. Pedrosa has undergone surgery twice in the past to rectify the problem, but he revealed that the issue still persists.
"Basically in this race I had an arm pump issue," Pedrosa said in the Losail paddock. "It's been now for completely one year. I start to have a lot of problems here [in 2014] so last year I struggled in every single race. I couldn't really perform well since then. My results have never been that good due to this fact.
"I've been trying all this time to fix it and to improve. It wasn't easy. I couldn't really get any good answers. I went through one surgery [after Jerez 2014]. It wasn't successful. I tried not to say in public, obviously it wasn't an easy thing. Honda always knew about it."
Pedrosa also revealed that he visited numerous doctors and specialists prior to the start of the season to see whether they had any answers as to why the problem persists.
"This winter I was travelling all around, trying to get many different opinions from several doctors," he said. "Trying to know if I can have a new surgery, trying to be ready for this championship. Fortunately all the answers recommended me not to have a surgery due to the risk of the surgery in that arm [making the arm pump worse]. I tried to follow this advice and work a lot in the non-aggressive [treatment].
"Which brings me back to today. We had this bad situation. I knew I wasn't feeling very well but anyway there was no other option for me. Now that the race is over and I can see that I cannot perform as I know I can, I have to decide to find a way to solve this problem.
Pedrosa added that he "cannot continue racing" until the problem is fixed since it will hinder his performance on the track.
"I cannot continue racing and performing this way," he said. "So my plan now is to try to fix my arm. I don't know exactly what is going to be. Because as I said the doctors don't know what to do. I will try to get rid of this problem. The team knows about it.
"Not so many answers for the moment. Everything is quite uncertain, obviously. I hope to have news soon. I will start again travelling and finding some results [from doctors]. I want to finish by saying thanks to all my sponsors to support me in this hard time of my career and all my fans. Obviously it's not the best situation from my side, but thanks to them for sticking with me."
