Hello, Sir Welcome to healthcaremagic. I can certainly understand your concern I have worked through your query in detail. I can assure that there is nothing to worry if you get your sensation after subsiding cellulitis, as you have already started on antibiotics, but if you cant regain your sensations or still feel numbness after, it is advisable to go for nerve conduction test to rule any injury to radial nerve, which supplies thumb and index finger Please check with your physician if he shares my view Post your further queries if any. Thank you
