Have side effects in the future....? thank you very much for the advice.
[|AI|]  Hi, From history it appears that he might have severe back muscle strain due to heavy lifting of weight of his auntie. Due to straightening of his back muscles there might be having spasm of muscles giving rise to this pain. Ask him to take analgesic with muscle relaxant medicine for 2-3 days. Apply some muscle relaxant cream on back. Having infection is less likely. Having any side effect in future is less likely. Ok and take care.
