Yesterday, I jumped out of my bed half asleep for some emergency situation and have hurt my back. I applied Nanofast gel (Diclofenac Sodium IP 10 mg, Methyl Salicylate IP 150 mg, Menthol IP 50 mg, Absolute Alcohol IP 50 mg) yesterday while going to bed. Today when I woke up at normal hours I felt quite severe low-back pain while I went to wash my face at the basin. I took a capsule of Raceclo (Aceclofenac SR IP 200 mg, rabeprazole Sodium EC IP 20 mg) after tea. While writing this question the pain has subsided but I plan to take another Raceclo capsule at dinner tonight. Is it OK to take two capsules of Raceclo in 24 hrs. Is it OK that I am taking Aceclofenac Slow release capsule? If not then suggest me some other generic drug and dosage. Also please suggest some exercise after the pain subsides. I have a history of low back pain and have taken medication for that previously. I work in BPO/ITeS sector and had to sit for 8 hours at a stretch in front of computers.
